If people don't want kids that is fine. But I do hope he has other family to support him and doesn't expect my kids or my kid's money to support him via social programs when he gets old.
That's not quite fair. The child-free pay for all kinds of things that they don't use nor will ever use -- schools, playgrounds, lunch programs, etc. etc. etc. Also, we don't get any tax breaks -- my marginal tax rate when you add it all up is nearly 45% I just got a small bonus and I saw about 1/2 of it.
I'll trade you all the money I spend on your kids now for the SSI I might get later.
