Yes, many can't afford childcare. In the Soviet Union, this wasn't a problem... but it was soon noticed that a paid childcare worker would not care for a child as that child's own mother would. Suppose that somehow you could pay for that. (probably not happening even for $million per year) Would you want it? Would you want your child to see someone else as, essentially, their mom? Who will your child love? Who will your child visit, decades later, in the nursing home? You can't substitute "quality time" for total time, simply being there for every skinned knee and question about life. Money isn't good at purchasing love, and you would be unhappy with the result if you succeeded.
