I left that morass in 1962 and never looked back.
The Peronists under Juan Peron is who started the mess in the first place.
The real reason for the collapse of Argentina has been it's socialized welfare system introduced by the Peronists in the late 1940's. Peron used the vast reserves that Argentina acquired during WWII by selling foodstuffs to establish a welfare state and buy out the support of the working class "Los descamisados" (the shirtless ones). He squandered it by buying out the foreign owned assets, such as the then British owned railway system which was in disrepair. Instead of attracting foreign investment and opening up the economy he nationalized industry. By the time of his overthrow in 1955 the country was bankrupt.
No goverment military or democratic has had the balls to tear down the welfare state. Instead they borrowed from the international markets to make up the budget shortfall to maintain a welfare state they could not afford. The country maintained a lifestyle without having the funds to pay for it. Instead of investing capital in productive activities they squandered it on the welfare system. Now they have to pay the piper and all the people who have been sucking at the tit are now having to realized the tit has dried up.
Argentina will never amount to anything unless it gets rid of the productive people paying for the unproductive. The real shame is the country is an immensily rich country in natural resources saddled by a population that is brain dead. But it will never change as generations of Argentines have been brainwashed into believeing they are a second world country, when in reality they don't even belong in the thirld world.
There is no alternative politically because the choice is between the left (The Peronists) and the farther left (The Radical Civic Union and Frepaso) . There exists nothing tantamount to any legitimate conservative laisez Faire parties
Look carefully at Argentina because that is where the welfare state eventually leads.
