Lately I’ve been noticing that the people who mainly should not have children, whether due to economic limitations, illnesses, or even mental instability, are the ones who have the most children, and many times they end up as single fathers/mothers. My question is whether it would be a good idea to implement some kind of regulation and set minimum requirements that must be met, mainly to prevent the child from ending up in the future as a criminal or a social burden due to those factors.


No government should do that. Just like no government should have the ability to parent your children. Unfortunately, lazy peeps want this so they can stick it to people who are actively parenting their children, because they can’t be bothered to do it themselves.
It could be worse, I’d bet that there are even those who would like the government to pay them for having children that they poorly care for.
