People say stuff like that all the time, then the most free market economy does well in the long term. Culture is important, but mainly as far as it permits people to freely help themselves prosper.
The West is made up of countries that often have 40%+ of their economy made up by government spending, ie, spending that wouldn't happen under a free market. That is far more a problem as far as raw economic outcomes than long- or short- term cultures. China will collapse if someone high up in the government attempts a 2nd Leap Forward, culture matters a lot in whether they tolerate a bureaucracy with that sort of power (history hint - don't tolerate that sort of power in the bureaucracy).
