The problem we have here in Argentina is not capitalism. The problem with Argentina is that we don't have capitalism.
Capitalist countries like Taiwan, South Korea, and the People's Republic of China (!) have gone from being much poorer than we are to being much richer than we are in only a few decades. Meanwhile Perón's "third way" between capitalism and communism has left us poor and economically stagnant. We have to constantly struggle against bureaucracy to do anything economically productive, and if that's successful, the government confiscates it. Only politically well-connected companies can prosper, and those mostly produce low-quality goods that people only buy because importing goods from abroad is prohibitively expensive and bureaucratic. The society is thoroughly corrupt, having internalized the lesson that when someone gets cheated, it's their own fault for being so stupid, and a laudable achievement for the cheater. So Argentines who have the choice invest their money abroad, leaving the country without the capital investment required for industrial productivity.
The current government says lots of great things about capitalism and economic liberty, but you cannot institute capitalism by fiat. (Turning a healthy tank of fish into fish soup is easier than turning fish soup back into a healthy tank of fish.) Capitalism is highly productive because capitalists invest their capital in creating productive capacity in the expectation of profit. In Argentina, capitalists very reasonably have the expectation that, after the next election, their profits will be confiscated by the new administration. So they don't invest, except in forms that pay for themselves before the next election — mining minerals and planting crops, for example.
Massive state spending to expand productive capacity might be able to break this cycle, following the examples of the US, the USSR, the People's Republic of China, and Perón himself (before he abandoned the policy). But it's absolutely taboo for both the current "libertarian" administration and their Peronist political opponents.
