If someone has the means to comfortably raise a child without being in poverty do they still need free childcare then?

Having an extra $2k/mo per child laying around puts you in a pretty high income bracket.

Often programs like this are subsidized based on income such that if they can afford it, it is subsidized less, or you do not qualify past a certain income. That is one method of managing the program's costs, while still benefitting those who are most heavily affected. This program doesn't appear to do that, but many do.

I am not sure what point you are trying to make though.
