It’s not really the “global financial system”, tax-funded pensions are mostly a richer-country thing. In less developed places, young people often “pay” for the elderly without ever giving them a tax dollar, e.g. by staying put to care for an elderly relative instead of moving somewhere with better pay or quality of life.
I'm glad you said "or", because in a lot of cases better pay does not lead to better quality of life, not until you've broken through to upper middle class and beyond and can choose how much time you spend on work or choose to live somewhere nice.
