Economist Stephen Moore said median family incomes for the middle class is up $4,100 since Trump took office

Economist and author Stephen Moore highlighted a new study that says the middle class is getting richer, faster for President Trump than it did for recent presidents.

Moore, who helped write the 2017 tax cuts, cited a report from the Census Bureau and said: 'Since Donald Trump was elected and took office through July of 2019, median family incomes, middle-class incomes are up $4,100.'

For the 12 months ending in July, the real median household income - those in the very middle - was $65,084.

Moore contends with such economic prosperity for households, 'If these numbers hold up, it’s going to be difficult for any Democrat to beat Donald Trump because he’s proven to be the blue-collar president,' he told Fox News.

One of those Democrats is Vermont Senator Bernie Sanders, who has made the gulf the between the wealthiest and the middle class his main campaign promise in 2016 and again in 2020.

The Sanders campaign says their plan would impact approximately 180,000 households nationwide and would raise about $4.35 trillion in government revenue by the 2028 budget year.

But compared to the last Democratic president, Moore said Trump has done much more for the middle class.

Economist and author Stephen Moore says middle class salary's under President Obama were four times lower than for families since President Trump took office

'In the entire eight years that Obama was president, incomes only budged up about $1,000, so in one-third of the time, Trump has increased income by four times as much,' Moore said. 'We now have a median income of 65,000 dollars.'

As posted on Twitter with a link to his Wall Street Journal opinion, Moore said 'the middle class is not only shrinking, it's getting richer' and because of that he congratulates White House economic adviser Larry Kudlow for agreeing that 'families are spending and saving more at the same time.'

But he ends the WSJ piece with a warning: 'A protracted economic slowdown or recession could reverse Mr. Trump’s advances on jobs and incomes. The trade war is imposing a heavy toll. But for now the median family enjoys its fattest paychecks ever.'
