> If you're 66 and you're still sitting around in a corporate job, and you have no children, 9/10 you're really just taking up space for someone who needs to feed their kids, has a potential to grow, and a better place to funnel the earned money than "expensive manicure"

That seems very judgmental to me.

I don't plan to have kids due to genetic conditions and other reasons, but by your reckoning, I don't deserve a job once I age because there are other people "more deserving."
