Capitalism is not reformable because it fundamentally relies on ever increasing rates of profit and exploitation. The first is impossible in a finite world, and the second is untenable to anyone who believes in justice.

I agree. The US have oligarchic crony capitalism supported by an utterly corrupt political system. Trying to abolish capitalism without restoring democracy and the rule of law is a fools errand. Not like it's never been tried. And every time it just replaced one ruling clique of assholes with another one.
