A excellent  argument can be made that Trump's election was based largely on the economy.  

The 1% did quite well starting with TARP (whether you give the credit for that to Bush or Obama) and ending with today's stock market during the Obama administration.

The 'left behind voters' who voted for Trump (against Obama-Hillary?) are categorized that way based on economics.

They, at least, answered Reagan's question "Are you better off today than you were [eight] years ago?" in the negative and voted Trump.

Those who love the racist, homophobic, misogynistic view of the world won't even acknowledge that possibility, of course.
