if korea (et al) are successful, fine; but its not successful on honorable reasons. it has been stealing jobs and there's no way to compete when you NEED healthcare in the US and that, alone, is enough to disbalance things unfairly.
I sympathize with your frustration, but have felt this for America likely long before you. The small Kansas town in which I grew up (pop. 150) flourished in my father's lifetime with a bank, hotel, drug store, barber, etc. But by my youth in the 1960s, only two repair garages and a tavern remained; essentially it was a ghost town, and even lost its high school. Thanks to the automobile and better roads (an ICBM station nearby got us asphalt roads), almost all the jobs were "outsourced" to the big city, Tokpeka. Then in my late adolescence the same happened to Topeka, when the Goodyear tire plant (once the largest in the world) scaled back its production, putting Topeka on the skids and the economic energy went to Kansas City, Chicago, and the coasts. And this was the 1970s. This hollowing out process due to changing technology, mobility of capital and labor has continued in the U.S. for the past century and likely will continue apace globally, as borders become less relevant. Some companies, such as Apple and Catepillar have been able have been able to adapt and create products desired around the world, others such Zenith and RCA have fallen into senescence.
I'm not sure what you mean by "honorable reasons", but the meme that Asians cheat at trade hasn't really been a fair observation since even the GATT says in the 1980s and certainly not since the WTO began in 1995. Basically the reason South Koreans got ahead was because even though they have few resources they worked harder than everyone in the world, saved as much as they could, and sacrificed for higher education. Among other things they created world-class steelmaking, shipbuilding, and semiconductor industries out of nothing, using mostly Japanese capital and technology, since the U.S. viewed them as foolish to have such ambitions from the 1960s.
At present, South Korea does more trade with China than the U.S., and they are one of the few countries that manage a balance of payments surplus with China because they produce goods that the Chinese want to buy. Moreover, the largest group of foreign students in China are South Koreans and the largest group of foreign students in South Korea are Chinese. South Korea remains firmly in the U.S. camp militarily and is grateful for the troops stationed here (though they get almost no credit in the U.S. for the sizable contingent of troops they sent to Vietnam and Iraq), but over time, the U.S. is gradually becoming much less important to the nation's future, as evidenced by the Free Trade Agreement (FTA) they recently signed with the European Union, while the prospective one with the U.S. is stalled, largely due to protectionist sentiments.
South Korea is by no means perfect and they go overboard at time on anti-American issues such as fears of beef BSE contamination, but on the whole they are a hard-working, highly educated people who deserve the success they have achieved by dint of great efforts over decades.
