This whole idea is stupid. How about giving proper financial support for parents and covering all expenses for raising a child and not just give away money to lazy people who don't want to work and contribute nothing to society.
The opposite would be better: give financial support to people only if they agree not to waste that money on kids they can't afford to have.
Unless you are implying that everyone is politically connected, I'll guess that you are just throwing any argument against a wall to see if anything sticks.
— like a universal basic income —

— like “investors' dividends”.
This argument makes more sense against capitalism than against this.
If you have extra money to give away then it is better to give them to parents to promote creating families, to pay for education for children from poor families, to improve free medicine, to create new jobs etc. It doesn't make sense to give money to people who are just lazy and got used to spending their parents' money instead of working. They will just spend money on alcohol, cigarettes or online games.
