I think the next generation are going to have it much worse. Unlike my parents generation there is far less job security, less pensions, less job mobility, and most likely less soc security at retirement. I wouldn't be surprised if the US becomes a land of the haves and (many more) have nots.
That's what I worry about. I think we have enough to retire and I know we have more than most people our age. But we "sacrificed" and lived beneath our means all of our lives and I just don't see people doing that now. My grandparent's generation were mostly immigrants and they were incredibly frugal, not just MY grandparents but almost everyone was that way in the 30s, 40s, 50s. My parents lived larger, always had retirement and social security to count on, and so forth. But they actually had/have that in most case. I just don't know about our and future generations that will have no safety net yet have learned to live large.
And they are the people who will be taking care of us! Even if you have plenty saved you'll still need the services of doctors, lawyers, nurses, etc.
And none of them will make enough to pay enough in taxes to maintain the country the way it is now. I think we are going to witness major declines in infrastructure, living standards, and stuff like that. We won't be living in squalor but I think everyone will look back on the last couple of decades as the golden age.
