The income gap between the classes is growing at a startling pace in the United States. In 1980, the top 1 percent earned on average 27 times more than workers in the bottom 50 percent. Today, they earn 81 times more.
The widening gap is “due to a boom in capital income,” according to research by French economist Thomas Piketty. That means the rich are living off of their wealth rather than investing it in businesses that create jobs, as Republican, supply-side economics predicts they would do.
Piketty played a pivotal role in pushing income inequality to the center of public discussions in 2013 with his book, Capital in the Twenty-First Century. In a new working paper, he and his co-authors report that the average national income per adult grew by 61 percent in the United States between 1980 and 2014. But only the highest earners benefited from that growth.
For those in the top 1 percent, income rose 205 percent. Meanwhile, the average pre-tax income of the bottom 50 percent of workers was basically unchanged, stagnating “at about $16,000 per adult after adjusting for inflation,” the paper reads.
It notes that this trend has important political consequences: “An economy that fails to deliver growth for half of its people for an entire generation is bound to generate discontent with the status quo and a rejection of establishment politics.”
But the authors also note that the trend is not inevitable or irreversible. In France, for example, the bottom 50 percent of pre-tax income grew by about the same rate — 32 percent — as the overall national income per adult from 1980 to 2014.
The difference? In the United States, “the stagnation of bottom 50 percent of incomes and the upsurge in the top 1 percent coincided with drastically reduced progressive taxation, widespread deregulation of industries and services, particularly the financial services…
