Asset price over median income

Generations ago, you were starting work at your early teens and working until almost the end. As technology advances, people can now start working later (school, studies), retire earlier (pension), receive benefits, or build enough assets and stop working. It seems we have various dials (political, cultural) to keep or enforce a relative balance of who gets the benefit of having to work less. Asset price over median income appear to be an financial tool that also affects this balance.
