I realize that expectation for elderly care varies across cultures, but even in industrialized Western countries, there's some expectation of adult children taking care of their elderly parents. So the argument that we should all pay for the next generation because we rely on them to take care of us rings a bit hollow. Is my neighbor's kids going to look after me when I get Alzheimers? I imagine not. I'll have to live with whatever service I can afford with my retirement account. For the childless, it's a choice they make to prioritize present comfort over future security. Parents are making the opposite tradeoff, but expect the childless to subsidize their present loss in time/money/leisure. How does that seem fair?
