The most glaring flaw I found in LaFollette's analysis is not the theoretical/philosophical case for licensing parents, but rather he struck me as somewhat naive about the realities of implementing a political policy. He asserts that there is no real reason why there would be more corruption in this realm of licensing compared to others, but this seems to neglect the immense power that somebody holds when creating this policy. Children tend to adopt the political and religious attitudes of their parents. If you control who reproduces, you can influence the political demographics of future generations. I think this potential would be very tantalizing to a lot of politicians, so it seems like there is a high risk of corruption or subtle biases in approval - much more so than the political influences of deciding who gets driver's licenses. I thought the article that Tresan posted was also revealing of the logistical issues of navigating governmental bureaucracy with this type of really serious policy. There's also the issue of the temptation to expand it beyond simply just an outright, obviously physically or emotionally abusive parent. For instance, there's a lot of parents that seem likely to be negligent or not ideal parents. The most obvious example that comes to mind is young teenagers. Do they still get a license if they just aren't violently abusive? Single 15 year old girls aren't typically ideal parents, and it feels very tempting to create restrictions against having children in that sort of situation, even if it isn't under a traditional definition of abuse. But, if we do that we will have more issues with infringing upon personal freedom even further and questions as to what it means to be a good parent. There are probably some teenage mothers who are very good parents, whereas older adults can still be irresponsible parents regardless of their theoretically increased maturity. And if we're expanding restrictions, there's all sorts of factions that yield a surprising amount of political power (such as Christian fundamentalists in the United States) or new-age millitant atheists who might believe that raising a child without/with a certain religious upbringing is abusive. The whole thing seems like it could get really messy really quickly.
I thought the notion of eugenics that got brought up in class was really interesting. I'm inclined to agree that eugenic tendencies could definitely develop from a proposal like this. But, I'm not actually sure that this is a bad thing (I know, I'm evil, but hear me out). Tresan mentioned that the screening test could just explicitly not look for genetic things that somebody doesn't really have control over. But, I don't think that this is necessarily a good thing. I had the impression that this proposal was about improving the quality of life for future people/those who don't currently exist. Even if a parent isn't trying to be abusive, knowingly creating a child who will suffer immensely with some type of genetic disorder is undeniably harmful towards that child. If we're already doing this policy, we could just be careful about what we select against, and only make it really severe genetic disorders which seem to almost undeniably impair one's quality of life that people wouldn't ever choose to have. Perhaps its horribly wrong and I'm just ableist and evil, but its at least not obvious to me why it would be so harmful to limit people from passing on really severe genetic disorders that make it impossible for people to live a normal life (perhaps the standard of being unable to ever support one's self independently). I kind of like it because it seems more objective and predictive than any type of subjective 'parenting' test would likely be. You could probably even find a potential genetic basis for violent/abusive tendencies.
I can't decide whether or not it would improve social attitudes towards parenting. Currently, I think many people have a very flipping towards the very serious undertaking of raising children. If we required licensing, it might make people think more carefully about the notion of having kids since they have to work a little bit harder for it. On the other hand, LaFollette continuously expresses how basic or easy to pass this parenting test would be. Unfortunately, those who hold licenses tend to be endowed with an (perhaps inflated) sense of competence. This could generate a very insidious belief that if one passes a parenting test to receive a license, they are entirely prepared, infallible, and qualified to a parent. Ultimately, I worry that this would detract from the very important understanding that parenting is very difficult and parents are undeniably going to make mistakes and will have to learn from their mistakes or modify their strategies. The only way to avoid this would be to make the test more rigorous, which has its own host of problems (namely, the difficulties surrounding deciding what it means to be a good parent). A weird idea I had for this type of test could be a simulation of sorts. That is, especially as we improve at AI, we could make a somewhat realistic 'robot' that the parents have to successfully 'raise' for a month (or 6 months or something) and grows up at an accelerated rate. It could try to simulate all of the obnoxious things that children inevitably do, and then measure/analyze parental responses to those situations. There can be more than one right answer, but this might be a revealing way to determine who is prone to violence or abuse. It also might encourage parents to carefully consider whether they truly want to have a kid if they've been exposed to the less idealized reality of it.
He also kind of glosses over the implementation of the policy, but I have some ideas. Obviously forced sterilization for those who fail is ridiculous and inhumane. The notion of just taking away the children of parents who aren't licensed might work, but should probably be kept to a minimum unless we make substantial improvements to our foster care system and increase adoption rates (which are relatively low). Otherwise, the child still has a heightened chance of growing up in a less ideal, unstable environment if they end up being passed around between foster homes often. I think his idea of financial incentives is far too weak to the point of almost making a policy meaningless - it seems like it would simply hurt vulnerable children further, since the children of those who do not qualify would not only grow up in an environment with a potentially abusive parent, but also deprived of additional resources. But, modern medicine is getting pretty good at modern forms of birth control. We already have a variety of methods, at least for female birth control, which can last up to 10 years (such as IUDs). We're also getting pretty good at injections, and that struck me as something that could probably be easily further developed if this policy started to get serious political traction (which it probably never will). They already have birth control injections for women that can last several months - we could probably improve this to last several years or more. There's also a form of male birth control in development called RISUG (reversible inhibition of sperm under guidance) which is essentially an injection which researchers believe could be effective for about 10 years. Perhaps (although this is kind of stretching it) if we could get it down to a very non-invasive injection, we could make it a really routine, normalized procedure kind of like vaccinations, and it wouldn't have to be very frequent ideally. Perhaps we couldn't quite force people to do it, but we could make it really normal/expected and make it inconvenient not to do so somehow. Then, if somebody passed their parenting test, they could have approval to get the procedure or whatever legally reversed. This whole thing still sounds like a political nightmare, particularly with the obvious infringement upon bodily autonomy that my proposal implies. Nonetheless, I think that if LaFollette and other proponents of this idea need to have some type of practical plan for implementing this policy if they want to be taken seriously and currently there is not an obvious proposal that seems politically and ethically feasible. It is a nice philosophical concept though - and, at least on a personal level, I'm inclined to agree that most people who have had kids probably really shouldn't have and probably really aren't qualified for that type of responsibility.
