How much of the monetary gains from the Trump economic speedup have gone to the middle class? If you ask Democratic senators and presidential candidates Elizabeth Warren, Kamala Harris and Bernie Sanders, the answer to that question is … almost none.
” [Donald] Trump’s economy is great for billionaires, not for working people,” Sanders likes to say. Meanwhile, House Speaker Nancy Pelosi grouses that under the Trump agenda, “the rich get richer, and everyone else is stuck paying the bill.”
Uh-huh. That’s been the standard liberal riff for the last couple of years as they try to explain how a president who they said would create a second Great Depression has created boom times with the lowest inflation and unemployment in half a century.
But not a word of this is true, according to new Census Bureau data on the incomes of America’s middle class. This study by former Census Bureau researchers and now statisticians at Sentier Research has found gigantic income gains for the middle class under Trump. The median or average-income family has seen a gain of $5,003 since Trump came into office. Median family income is now (August 2019) $65,976, up from about $61,000 when he entered office (January 2017).
Under George W. Bush, the household income gains were a little over $400 in eight years, and under Barack Obama the gains were $1,043. That was in eight years for each. Under Trump, in less than three years, the extra income is about three times larger.
Those are just the flat dollar amounts. What you want is the Real median income (www.multpl.com/us-median-real-income/table/by-year)
Bush: 58,544.00 to 56,076.00
Obama: 56,076.00 to 59,039.00
According to that site, at least.
