Interesting charts. My only quibble is with assessing income as opposed to net worth. I make a decent salary, but as Howlin' Wolf sang,
"Now looka here, I did not say I was a millionaire
But I said I have spent more money than a millionaire
'Cause if I had've kept all my money that I'd already spent, I would've been a millionaire a looong time ago ..."
He (probably) wasn't buying Aldens, but this QFT.
edit: mcarthur you beat me to the punch
