My mother barely thinks about her future. She probably is implicitly believing I will handle all living costs once she retires.
So yes, unless you have a rich family, if none cares about who gonna do work in the future, everyone will die in poverty, and i deeply despise poverty.
I would pretty much just be dead than being (too) poor.
But second to the financial issues, lack of perspectives is an easy ticket to depressionville
In that case, it's a "don't do" for people who can't afford it. But not really a bad choice for people who can.
There is a lot of benefit from not needing to pay for rent/mortgage/kids etc. Mostly you have extra free time and money to spend on personal hobby because you can retire early.
Google lean FIRE, it's basically a life style that spend as little as possible, put all the money on passive income assets, so one can retire early and be free from working, while accomplish whatever they want in life.
Having kids/mortgage/rent etc will make lean FIRE much harder to accomplish at early age. Such extra spending will create a large hole in your pocket.
It's not the life choice for everybody. But it is not an inherently a worse lifestyle. It's one life choice out of many.
I know plenty of people who retired at 35-40, only because they have no extra financial burdens like kids or mortgage. They can retire early only because they did all the "don't do" from this video.
