Design Economics to Avoid Poverty

Social Welfare Proportional Children Program Single Child Program 1 child $ $$$ 2 children $$ - 3 children $$$ - ... ... ... n children $...$ - Should a nation give money, for a family, to raise children? In Brazil, there is a social program (Bolsa Família) that gives a small amount of money for each child (of a poor family). When the nation gives a large amount of money, there would be some issues: The nation may not have enough money (for all the families). Each family may have as many children as they could. In China, there is a law about "every family can have only one child". In Western Nations, families can decide how many kids they have. A solution for this question could be: "For the first child, the family will receive a large amount of money (from the nation) to raise the kid. For all the other children, the family will have to raise the kids with their own money.". After a few generations, maybe poor people could learn how to raise kids (without the money from the nation).
