Oof. Check out what retirement ages were in the USSR. They were very similar to China with options to retire earlier if you worked more physically demanding jobs.
Turns out retirement ages in the imperial core have always been worse and since there is no big bad red to be scared of, the capitalists don’t feel the need to make the same kind of concessions they needed to make to prevent similar uprisings in their country in the past.
Your life is being stolen from you for someone else’s profit. It will always be this way under a capitalist system.
