See Hitler's American Model (2017) which talks about how Nazi lawyers were attracted to how the US built itself on the tradition of common law as opposed to the more European and relatively inflexible tradition of civil law. Government under common law may change rapidly as judges overturn precedent, opening a window for demagogues such as Trump a way to quickly reform government in their favor before a majority of the populace, with their often passive consequence-centered de facto method of understanding political decisions, can oppose the changes.
What absolutely. Fascism is in many ways the natural trend of the state under capitalism, and the US is the State of capitalism. It's inherently reactionary and opposed to socialism on a fundamental basis.
What's happening in the US comes from broken institutions, extreme polarization, and uniquely American political problems - not capitalism itself. Look around: plenty of countries more capitalist than US (Nordic nations, Switzerland, Singapore) have solid democracies without sliding into fascism.
You're confusing economic systems with political structures. The issue isn't free markets; it's the specific American mess of corporate money corrupting politics and the eroding checks and balances.
I'm so tired of people blaming capitalism, it's like blaming hydration for drowning. Makes as little sense.
