I offer you a counter-theory: Donald Trump will use his administration the same way he used his business empire, following the same pattern of behavior in the white house. He will use the office of the presidency to push business deals, energy investments, defense contracts, he will push for more and more privatization of education and sweeten the pot for the health insurance industry, all while expecting -- if not outright demanding -- kickbacks from those industries in the form of partnerships with his businesses and his own investments. All of this while at the same time sucking up to evangelicals and white nationalists to get them to donate to his reelection fund and help finance local pet projects that fall in line with his overall agenda. He will in various nonsensical ways spit rhetoric about how everything he's doing is good for America and good for the economy and will continue to profit off his actions, paying no attention to legality or decorum, attack and denounce his critics, and pretty much do as he pleases.
Like a new manager who hires all of his home boys to run the store, the result is a tidal wave of graft and corruption, with the most aggressive and ambitious individuals ending up in positions of power. Those same individuals are then free to use those positions to pursue longstanding grudges against their rivals (white nationalists, teabaggers, anti-abortionists, homophobes, nativists, etc) and with no one to reign them in, it's open season on everyone who dared speak up before.
I'm sure that'll be GREAT for the middle class.
