“ ‘The Dow soars, wages don’t.’ ”

That’s “inequality in a nutshell,” according to Rep. Alexandria Ocasio-Cortez, who fired off those words in a tweet response to NBC’s coverage of a fresh high for the Dow Jones Industrial Average DJIA, -0.87% on Friday.

The New York Democrat was making the point that while the blue-chip index rallied more than 20% last year, U.S. average hourly earnings gained less than 3%. And since stocks are generally held by those with higher wealth levels, the data would support her “rich getting richer” stance.
