“In 2009 alone, at the same time as the US was being convulsed by mass layoffs, the number of millionaires in the country skyrocketed.”
That is because jobs are being replaced by those who are currently innovating and the innovaters are yet again making money off of their creations. No different than Facebook doing better than MySpace because Facebook offers more and is more polished.
And owing to inflation, a million ain’t what it used to be.
Soon, even the poor will be “millionaires”.
