I would say that the Tarrifs are a further attack on the working class as they were back then. Another tool to consolidate capital.

The largest difference today is the financialization of our economy (basically meaning every company runs like a bank). This had been a method of consistently allowing the contradictions of capitalism to be delayed and passed off through layoffs and stock buybacks to further sustain the bubble of this system.

It’s almost impressive at how well capitalism has adapted throughout the centuries to suck more and more away from the working class before it has to deal with a potential revolutionary “breaking point”. It’s definitely something Marx could have never predicted.

TLDR: I would not say that tarrifs are the cause of either of these events. I would say they are a tool of the ruling class to be used in times that capitalism hits a crisis. The cause is capitalisms contradictions itself. These extreme tarrifs are just a tool to attempt to deal with those contradictions.
