The yuppies are just the lowest ranking plutocrats, trying to rise, but they didn't invent the game.
Ma Nature does a lot of tinkering, and besides Aspies, she produces psychopaths. In tribal times, there would usually be at least one of each per village. The aspie would do the tech R&D, and the psycho would get extra management to keep them in line. However, if disaster struck, the psycho would seize power, and organize the survival of half the tribe, when an NT would have refused to abandon the weak, and lost almost everyone.
Once the R&D had discovered irrigation and grain farming, we had to get along in larger political units, because those who farmed quickly outnumbered those who did not. Concurrently, R&D found how to use clay to keep the mice out of the grain, and we began to stockpile surpluses against the thin years. The psychopaths found that by taking over the job of minding the grain, and managing their image through layers of authority, they could tickle our "crisis" response enough to stay in power.
The history of civilization is also the history of the psychopaths forming loose gangs, and treating the rest of us as stupid domestic animals who are not as ruthless as themselves. So, yes, you are a slave of the yuppies, but they are also low-ranking slaves, being selected according to their wiles. To win at their game, they have to cheat you at every opportunity.
