copy past from a comment I made elsewhere:

but those ambiguities aside, there is another notable discrepancy between modern american and weimer germany, the support of big business.

first I will admit to being nothing more than a layman on this topic, so there could very well be ways I am misunderstanding or misinterpreting the information.

The industrial petition, the circle of friends of the economy, and the Secret Meeting of 20 February 1933 (that last of which involved industrialists giving 8.9 million 2017 euros to hitler to help him pass the enabling act) show this off.

Take a look at the occupations of the people involved, and contrast that with this article where many business leaders denounce the recent events, some referencing trump explicitly.

There might be a paywall stopping you from reading it (if that's the case, i recommend this), but it includes people and organizations like, jamie dimon, Business Roundtable denouncing the riot and calling for a peaceful transition to Biden's administration. The National Association of Manufacturers, a long-time ally, rebuked trump, and the head called for the 25th amendment to be applied. Not everyone in the group agrees, but:

Mr. Timmons acknowledged some dissent. “We’re a diverse organization. Not everyone’s going to agree with every word I say on behalf of the industry,” he said. But, he said, “we have had overwhelming — stunningly overwhelming — support from the membership on the statement.”

Why the discrepancy? Again I'm only a laymen, but from what little I know the background of all this was the great depression, which exacerbated tensions from an already strong labour movement, political instability (relating, among other things, to the very way parliament was constituted which made for short lived coalition governments) and presumably some other things.

In addition trump lacks anything like the brownshirts, a paramilitary unit for the defence of nazis and intimidation of others (including the paramilitary units of the left-wing SDP and KDP, which also have no contemporary analogue) At it's peak, near the end of 1933, it had 3 million members, while the german army was restricted to 100,000 by law.

With all this in mind, I don't think there is any feasible chance that trump's faction will be able to rise like the nazis did. There can be no certainty about what the future holds, and what will come after trump, so I cannot say with certainty that american democracy will survive for years or decades to come (although i'm fairly confident it will be around at least for the next several years) but if we are to compare weimar germany with contemporary america, we should also point out the discrepancies.
