That is because, speaking as one of the two parties of Wall Street and big business, the Democrats are just as terrified of, and hostile to, the growth of mass popular opposition to capitalism as Trump is.
There is an element of truth in Trump’s apocalyptic warnings about the rising tide of socialism. The fact is that Trump, hiding in his White House bunker, really is besieged by socialist sentiment all around him. The American working class, devastated by the economic crisis, increasingly hostile to the back-to-work campaign that Trump is leading, and ever more explicitly hostile to capitalism, is emerging onto the political scene.
It is this social force, not the spineless Democratic Party and the factions of the affluent upper middle class and Wall Street it speaks for, which is the real opposition to Trump’s efforts to create an American fascism.
