Convict you in absentia then use the judgement as an excuse to freeze your bank account and ban you from all forms of banking (something that the US has the power to impose on foreigner because they hold every western bank by the balls due to their reliance on the fed)?
I don't know if they would do it, but it certainly wouldn't be unconstitutional; the US have long made it clear that foreigners on foreign land don't have any legal rights whatsoever. I would be having a long conversation with lawyers to get some hard assurances before going down that path.
"We're too poor to afford to risk anything" is insulting to all the popular revolutions which happened because people were actually poor. Like, sorry not sorry, but the median American proletarian may live paycheck-to-paycheck but still lives in untold luxury compared to a 1917 Bolshevik who had to go to war sharing two boots and one rifle with multiple people, or the median revolutionary in Nepal last year (one of the poorest countries in the world).
Americans really have it too good to risk it all, that analysis is correct. They could have it a lot better, sure, but threat of not having it so good anymore is what keeps them complacent.
