But what these parents receive is humanity, not privelage

You've just made it worse. You've gone from "Parents receive privileges that non-parents don't" to "Parents deserve more humanity than non-parents," then you compare non-parents to the mentally ill:

This is like a rich person complaining about poor people receiving economic support

I am in favour of Universal Basic Income, the first word of that being universal. Let the rich person have a drop in their bucket while providing the basic needs of living to everybody.

You say “it takes a village”

When did I say that?

but how are you, as a childfree person which is complaining about others receiving aid that you yourself do not need

What makes you think I don't need a flexible schedule or the ability to turn down traveling for work?

being part of said village? What is your contribution?

As established earlier: Taxes that fund schools and safety nets.
