We are leaving out the 300 years of colonialism. And 50 years of socialism. 30 years is not enough to move a billion people out of the ills of socialism and colonialism
The US stopped interfering in South America by the 90s. By your own logic, how long do the socialist countries in South America need to recover from US interference? 10 years? 30 years? 100 years? 1000 years?
>In response to your edit: "Currently a majority of North Koreans are dependent on markets for their survival." See https://en.wikipedia.org/wiki/Jangmadang. North Korea is also a market economy.
You are missing the point here. The illicit market economy is what is helping them survive the legal socialist economy. Thank the market economy for saving the NK.
> In what way has the US interfered in South Korea or Japan since 1950? How does that compare to being sanctioned and embargoed by every major Western nation? Would you like to hear about Cuba instead?
Care to tell me first how the US has interfered in Mexico?
