This is a rather uni-dimensional and, might I say, judgemental view of the CF movement. People choosing to be child-free just want to have "no responsibilities, FIRE, and never give to anyone but themselves" - really? What about women finally taking agency and rejecting the belief that they must have kids to be fulfilled? You also seem to completely ignore the economic state of the world. The economic conditions we grow up in leave a psychological imprint and influence the choices we make, even as adults.

I have the utmost respect for people with kids, but I also think that an individual needs to be 100% ready to have one, and not just reproduce because it would somehow provide them with a purpose.
