The cost of living has increased proportionally, not exactly leaving a lot of room for additional retirement savings.
Plus, proper retirement saving is hard. Saving 10% in a method that negates inflation only nets you 4.5 years of income at retirement age. You’ll need to drop your living costs by over 3x to live to a median age, unless you don’t retire in the traditional sense.
I don’t even see that much early retirement, instead of getting our mountains of things.
Or is this advice only for the proletariat, who for some reason will behave differently?
