"It Can't Happen Here" ? Fascism USA Style?

By Andrew W Taylor
Sinclair Lewis the progressive US novelist wrote a book entitled _It Can't Happen Here_ in the 1930s. In
his novel Lewis configured the elements he saw in a near-future US gone-wrong that were conducive to a fascist movement taking state power.

What are the elements in contemporary America which may be laying the groundwork for the creation of an encroaching fascism? (This question does not imply that fascism is inevitable in the USA, and, certainly, other forms of state-capitalist polity are possible.)

1 Systemic Economic Crisis
2 The handing over of partial ownership of Hi-Finance to the State
3 Widespread Civil unrest
4 A militarized society prepared to use Martial Law with its suspension of habeas corpus etc.

5 A weak Labour movement
6 A conservative social-democratic party which opposes socialist elements gaining power

In his last pamplet Leon Trotsky spoke to American workers stressing that fascism was not an inevitable development.
"...Especially Important to US Workers:
In every discussion of political topics the question invariably flares up: Shall we succeed in creating a strong party for the moment when the crisis comes? Might not fascism anticipate us? Isn’t a fascist stage of development inevitable? The successes of fascism easily make people lose all perspective, lead them to forget the actual conditions which made the strengthening and the victory of fascism possible. Yet a clear understanding of these conditions is of special importance to the workers of the United States. We may set it down as an historical law: Fascism was able to conquer only in those countries where the conservative labor parties prevented the proletariat from utilizing the revolutionary situation and seizing power..."
