alt Hacker NewsNations and companies try "financial incentives" for a bunch of fun stuff. It simply cannot be trusted.
Let's look at Hungary: loans unless you have 3 (!) children, maybe some housing subsidies that require you to match them with a huge chunk of your own money. Small wonder why that didn't motivate many people.
The problem is a country does not want to incentivize producing kids, that would be simple. Pay people $100k per child, and you’ll have a ton of children.
What countries do want is to incentivize production of properly raised, well mannered, productive children. And the type of person incentivized by a lot of cash to have a kid is probably not going to be the one to do that.
