I feel as if I've been reading some variant of this for the last 30 years (not just American, UK too).

But then what of it? I had more money at age 20 than I did at 15, more at 25 than 20, more at 30 than 25, and so on and so forth.

When I'm 70 I'll have more in real terms than I do now. Each year, barring some sort of disaster, most people work and bring in enough to survive whilst the surplus stacks up.

The main difference in my mind driving the rate of change in the proportions is just that the median person is more aware of things like the stock market, real estate, etc, now.

Basically, people are acting more efficiently. I'm more savvy than my parents were; they are/were proper working class "spend it as soon as it comes in, it might be gone" whereas I'm more like "never touch the capital, diversify".

(There are some issues, like how in the UK pensioners are given _extremely_ generous benefits, but I don't think that's relevant to the global picture).
