Back When Being a Millionaire Meant Something

From the 1930 blog:

"A record 511 people reported income over $1M in 1928; 26 reported income over $5M, with 11 of those in NY State."

Compare that to this, from Business Week (Bloomberg):

"The 400 highest-earning U.S. households reported an average of $345 million in income in 2007, up 31 percent from a year earlier, IRS statistics show."

So the incomes of the rich have multiplied many times since 1930.  (I won't give a multiple because the figures are apples and oranges.)
