Part of the secret is a big pocket book via gov't subsidies.
Last I checked South Korea is not big on natural resources like oil, gas, or precious metals. Not a big farming state, and not a great tourist destination either. Money comes in from industry so I am having a hard time seeing how the government would subsidize their industry when inudstry is where they get their revenue from!
There is the one fact that we pay for their military, have been for decades (don't go blaming Obama, he's the one that cut it back). So if there is a subsidy going one some place it is from us. LOL
