You can have the best working conditions in the world, it still sucks to have to work if you don't want to.

Some of us are fortunate to have jobs that we enjoy but the majority of people don't really want to work. They work to survive. That's just life.

Well yeah but then your problem is the fact you have to work at all. I doubt any modern societies have solved the issue of needing people to work.

Sure, but modern societies have solved the problem of needing to work until you're 70. Working until 65 or whatever still sucks, but 5 years is 5 years is not nothing.

It's the 5 best years that you have left to live. It's not nothing indeed.

I get it but then we should be moving towards less mandatory work, not a 70 years old retirement age.

Work isn't mandatory. You're free to stop any time, and accept the consequences of that choice.

What we should be doing is aggressively cutting the cost of living so that people who want to can afford to retire while still maintaining some reasonable quality of life. The number one thing that would help is to set policies that make it easier to build more housing because that's the largest expense for most people.

Life expectancy increases 5 years and pension age is increased by 10.

What? Already 100 years ago the retirement age in many countries was at around 65 years. https://en.m.wikipedia.org/wiki/Retirement_age

Well, yeah, life is largely about work. Retirement and living very comfortably off of one's savings/pension is a rather new phenomenon, and I'm not even sure it's a good one (in terms of health impact).
