Back in 1914, Henry Ford announced he was paying workers on his Model T assembly line $5 a day -- three times what the typical factory employee earned at the time. The Wall Street Journal termed his action an economic crime." But Ford knew it was a cunning business move. The higher wage turned Ford's auto workers into customers who could afford to buy Model Ts. In two years, Ford's profits more than doubled. Yet in the years leading up to the Great Crash of 1929 [the] wages of most American workers stagnated even as the economy surged. Gains went mainly into corporate profits and into the pockets of the very rich. American families maintained their standard of living by going deeper into debt, and the rich gambled with their gigantic winnings. In 1929, the debt bubble popped. The same thing happened in the years leading up to the crash of 2008. The lesson should be obvious. When the economy becomes too lopsided -- disproportionately benefiting corporate owners and top executives rather than average workers -- it tips over. It's still lopsided. We're slowly emerging from the depths of the worst downturn since the Great Depression, but nothing fundamentally has changed. Corporate profits are up largely because payrolls are down. Even Ford Motor Company is now paying its new hires half what it paid new employees a few years ago. All over the American economy, employee pay is now down to the smallest share of the economy since the government began collecting wage and salary data 60 years ago. And corporate profits constitute the largest share of the economy since then.
