First off, I asked an honest question to people of a generally different persuasion than me, so if I haven't been forthcoming in this thread, then there is an obvious reason.
Secondly, yes, there is a lot to be learned from history when we think about the current issues. Is that weird? I'd say these lessons are an 11 out of 10 in importance. Your reticence on this issue smacks of leftist presentism... which is interesting.
My problem with the general Keynesian framework is that I don't think it'll work today without serious restructuring since the North Atlantic countries no longer have colonial hinterlands (in the same way they used to... does colonialism still exist? yes, obviously, but it is very different). And yet, the collective imagination still seems pretty limited to a Deregulation+Privatization vs. Spend+tax sort of thing.
I'd rather see "stimulus" money go directly to keeping people in their homes + to debt forgiveness (and, yes, there is a history for that too:
https://www.amazon.com/Debt-The-First-000-Years/dp/1933633867) + economic protection for collective ownership ventures.
I'm not 100% sure I understand the question i put in bold, so I'll wait for you to clarify. If you want more than I've given above, then I'll provide more. But, seriously, I'm still working this stuff out.... that's why I'm asking questions.
