Here are a few good examples of "free market" vs. "socialist" economic structures and you can understand the results pretty easily. Certainly, they're not "Austrian economics" countries, but the examples exemplify the principles of markets vs. coercion which is at the core of Austrian ideology.

- North Korea vs South Korea
- East Germany vs West Germany post WWII
- East Germany under USSR vs. East Germany after unification
- Haiti vs. Dominican Republic
- Cuba vs. Costa Rica
- Any Chinese City vs. Hong Kong
- China vs. Taiwan
- China under communism vs. China today
- India pre-market reformations vs. India post-market reformations
- Any Malaysian City vs. Singapore
- Vietnam vs. Singapore
- UK vs. Ireland over the past 20 years
- Chile pre-Pinochet vs post-Pinochet (not that Pinochet wasn't also a violent douchebag)
- Venezuela vs Chile
- Zimbabwe vs South Africa
- Burma vs. Thailand
- Syria vs. United Arab Emirates
- Communist Estonia vs. Post-USSR Estonia
- Soviet Russia vs. Russia post 1989

And surely I needn't mention US history from 1776 up through about 1920, when it was actually a generally capitalist, free-market nation and grew from mere peasantry to the world super power in 150 years.

Every single example above compares a territory that is/was more centrally planned vs a territory that is/was more free. This list doesn't prove anything, but you might want to take note OP.
