No, peron was more of a corporatist/caudillo. As I recall, although he was as much a socialist as anything at times, he was usually more of a corporatist (an essential economic element of fascism), but heavily nationalist at all times (another essential element of fascism), and always a populist. peron’s own example is part of what gives rise to the existence of a rightist Peronism, and a leftist Peronism.
True.
It is an unfortunate tendency to treat Marx as some sort of defining point, and everything is either Marxist or not.
Marx was just one political theorist, and there was a left wing and there were statist systems before Marx and after him, that owed him nothing.
There are innumerable bad ideas that didn’t come from Marx.
Didn’t he seek to nationalize the banks, and other industry?
