Don't worry. In a decade or 2 Argentina will be fine. At least that's what happened in neighboring Chile.
In Chile, we helped Pinochet overthrow the government. Thousands were killed. Economic disaster. Fascism. Chicago School economics. And . . . Poof! . . . 20 years later Chile's economy was strong. The survivors and those who got rich were happy.
That's the cool thing about lethal policies. The people who die or are locked up can't vote against those in power. And eventually there will be a good economic cycle, so the PTB can crow about their good policies.
