Roughly 80 percent of millionaires in America are the first generation of their family to be rich. They didn’t inherit their wealth; they earned it. How? According to a recent survey of the top 1 percent of American earners, slightly less than 14 percent were involved in banking or finance.

Roughly a third were entrepreneurs or managers of nonfinancial businesses. Nearly 16 percent were doctors or other medical professionals.

Lawyers made up slightly more than 8 percent, and engineers, scientists and computer professionals another 6.6 percent.

Sports and entertainment figures — the folks flying in on their private jets to express solidarity with Occupy Wall Street — composed almost 2 percent.
