According to google, "approximately 57% to 67% of American adults are living paycheck to paycheck."

This doesn't mean they are poor. As their income goes up, so does their spending.

Also according to google, "Approximately 60% to 80% of professional athletes face severe financial distress or go broke within a few years of retirement, particularly in the NFL and NBA. Data suggests 78% of NFL players experience financial hardship within two years of retirement, while about 60% of NBA players are broke within five years."

and:

"though often debated, statistic suggests that up to 70% of lottery winners go broke or face financial distress within three to five years, more conservative estimates indicate about one-third (roughly 33%) declare bankruptcy."

Personally, I think that high schools should have a required course in finance and accounting.
