One of the most interesting culture in South korea is that under treated low class people (dirt-spoon class) don't really try disrupt current society model. To elaborate, people put poverty on their own responsibility rather than complaining about structural inequality. The rage towards class inequality is emitted at competition for higher ranked university and the reward of being in a prestigious college.
Always and everywhere the people at the bottom of the class hierarchy have enough problems that complaining about inequality or engaging in politics is not a priority. Social unrest is always about conflict within the elite or wannabe elite. The American Revolution was led by the richest of Americans. The French Revolution was led by the highly educated as was the Russian one. We have one historical example of a successful slave rebellion, in Haiti, and it was led by the most educated, cultured section of the free black population. For less violent examples look at the Labour Party in the UK, whose policy stance has almost always been that of the Fabian Society with some lag. A working class mass movement millions strong and what amounts to a debating/social club with well under a 1,000 truly active and engaged members had at least as big an impact on policy as the entire trade union movement.
