I don't think people should just have any number of children they want without being able to afford it, just because "they like kids". The society should offer some help, but most of the financial resources need to come from the parents themselves. You can't barely make minimum wages and have 8 kids. It is not fair to the kids, nor to the taxpayers who are forced to support them.
Honestly, I think that 90% of the world's problems can be attributed to people having more kids than they can support. It's a self-perpetuating cycle.
Too many kids -> parents have less time/energy to work, reducing income and causing poverty
Too many kids -> less resources (food, education, parental time, etc.) spent on each kid, causing the cycle to perpetuate by ensuring the kids will be in a low-education environment/not learn how to succeed/ not learn long-term planning/more likely to have kids themselves earlier
More kids -> younger population -> more conflicts/wars/radicalism (middle east and sub-saharan africa are political hotspots and both have some of the world's youngest populations). Middle-aged men with kids, careers, and mortgages don't go off and wage jihad. Political instability also causes more poverty.
China acknowledged that overpopulation was a big problem for its economic development. A few decades after the 1-child policy and its growth has been explosive. More countries should follow its example, there's no way that the planet can support 10+ billion people.
Not that this really applies to developed countries, which already have sub-replacement fertility rates.
