Not sure who needs to hear this, but...
GenX are not "Boomers" AND
Most of us work full time, so yeah, we can't just drop what we're doing to babysit, even if we'd like to (and unless you're one of the little shits constantly blaming us for your woes, or cutting us off for how we vote, or talk about individual rights, we would love to help)
We've been told since we were KIDS we were paying into something we were unlikely to get when we were old.
We have paid for "boomer" retirement benefits AND millennial college loans AND "stimulus" packages AND bailouts AND Medicare Part D, and SNAP and SCHIP AND Obamacare subsidies.
AND we aren't walking around expecting our kids will take care of us when we're old (in part bc they're constantly reminding us that they can't/won't and we better have a plan) so we're trying to work as long as we can and stay as healthy as possible so they don't even have to worry about it.
We are also the generation that had kids later, couldn't afford to buy a house until our mid to late 30s, and has kids who are more likely than any prior generation to not even want kids, so worrying about grandkids we may or may not have isn't as top-of-mind as one might think.
Worrying our kids' generation will adopt MAID and make it mandatory for us once we hit 72 "to combat climate change" or some such, *is*
But tell me more about how "selfish" WE are.
