Fertility rate may be important but to me it's not worth restricting (directly or indirectly) people's personal choices for. ... I think it's better to encourage people who are already interested in having kids to do so, through financial and other incentives.
Providing financial and other incentives to do X, if provided by the government, mean higher taxes on people who don't do X, an indirect restriction on their choices.
I did a sort of version of this for many years. Eventually it became a huge amount of somewhat painful work and it was never exactly clear to me how many people it was helping; it got a lot of karma, but so did a lot of much lower effort posts, and I didn't have a lot of other feedback mechanisms.
Thanks for sharing this!

Buying a coal mine ( a common occurrence that normal people do, though it turns out Will misunderstood the process in a way that probably invalidated the plan ) seems sufficiently different from buying a country ( a very rare occurrence with no established process, normal people do not do ) that I don't think you should take Will's serious interest in the former as much evidence about the latter.
I thought the first upskilling grant took place in early 2019?
Arguably the Lauren Lee grant also qualifies.
