Possibly so, though some more good years would be nice, to say the least. To some extent this could be noise, or delayed catch-up growth. Still, there seems to be a break in the previous trend:
In 2015, median household incomes rose by 5.2 percent. That was the fastest surge in percentage terms since the Census Bureau began keeping records in the 1960s. Women living alone saw their incomes rise by 8.7 percent. Median incomes for Hispanics rose by 6.1 percent. Immigrants’ incomes, excluding naturalized citizens, jumped by over 10 percent.
The news was especially good for the poor. The share of overall income that went to the poorest fifth increased by 3 percent, while the share that went to the affluent groups did not change. In that year, the poverty rate fell by 1.2 percentage points, the steepest decline since 1999.
…The numbers for 2016 have just been released by the Census Bureau, and the trends are pretty much the same. Median household income rose another 3.2 percent, after inflation, to its highest level ever. The poverty rate fell some more. The share of national income going to labor is now rising, while the share going to capital is falling.
That is from the new David Brooks column.
