Except the people going to work in old people's homes will not be the same people as it used to be. There are already many cases of blacks killing or mistreating white elderly in their homes. Over the recent months it should probably include Asian elderly now too. Also, you have lot's of news articles saying that pensioners are a tax burden on the populace. It's ironic. They spent their entire lives paying for this and they're treated like trash. Meanwhile, foreign groups who don't pay back the system and are a worst burden on the tax payers get away from any criticism. Many people say they deserve it, but I think they were too kind hearted and easily mislead. The treatment of the elderly is only going to get worst along with the treatment of the population.I've always thought one of the big pusher for reproduction is selfish self-preservation on a base personal level.
As you grow old you'll want someone to see you through your last years.
In that sense, I believe the only reason we can take the luxury of choosing not to have them is that we can find our way into an old people's home with a nurse or something.
In a way I believe child-free is slightly parasitic as eventually we'll live off the benefits of a society we're not helping to continue in the most meaningful/involved way we can.
If I couldn't go to an old people's home, huh... I would probably have kids, it's not guaranteed they'll take care of me but generally I guess all the living adults would employ society wide "conditioning" based on self interest to bully our little and then not so little slaves into seeing us through.
