This has been demonstrated many times. Including in the United States of America Yet socialists, statists, communists keep denying it.

When Pinochet's government slashed tariffs from an average of 94% down to 10% between 1974 and 1979, Chile ran a controlled experiment that statists still refuse to grade honestly.
The Chicago Boys, possibly the coolest name in history for a group of economists, were Chilean economists who trained under Milton Friedman at the University of Chicago. They dismantled price controls, privatized state enterprises, and opened the economy to foreign competition. The results were not subtle. Between 1976 and 1980, Chile's GDP grew at roughly 8% annually. Poverty rates fell. Consumer goods that previously required government permission to import sat on store shelves at prices ordinary Chileans could afford.
Compare that to what came before. Salvador Allende's government had nationalized over 500 companies and driven inflation to 600% annually by 1973. Shortages everywhere. Bread lines were real. The black market was the economy.
When bureaucrats stepped aside to let the market do its job, the economy flourished, as always.
Critics fixate on the Pinochet dictatorship, which carried genuine atrocities, and use those crimes to dismiss the economic liberalization. Political repression and free trade policy are separable facts. You evaluate them separately and the economics worked. The political violence was inexcusable. Both statements survive scrutiny without canceling each other.
