Spurred by a bustling global economy that includes $17 trillion in new valuation and record highs for American stock markets, low-income earners in America are seeing their wages increase at a faster rate than any time during the last decade.

Last month, the lowest 25 percent of earners saw their wages increase by 4.5 percent as compared to November of last year. The top quarter of wage earners saw a smaller increase of 2.9 percent from last year.

Another factor driving up wages for all workers was a tightening labor market, in which higher employment means any one employee has higher bargaining power than he would if more workers were unemployed. In October, U.S. unemployment hit a 50-year low.
