One thing also that must be understood is that just as there is a black market at the bottom, there is one at the top...
The difference in effective wealth
between a DuPont or Rockefeller and a successful trial lawyer is greater than the difference between that trial lawyer and a homeless bum. Far greater. The power curve looks like a capital J. I feel safe in saying that no one reading this is on the vertical part, or even on the curvy part, most likely. (which starts when you're dealing with multi-millions, I think)
We're almost all proletarians, here. Fighting the upper middle class as a class enemy is pointless.
Trying to forge solidarity of interests may go farther, but it's still a tough battle within the Spectacle.
(If the House Slaves identify with the Masters, it makes a slave revolt harder to pull off.)
This may change as "the economy" (which is many different things depending on who is saying it) gets more strained.
The government is often driven to suppress the upper middle class in order to create more equality among the proletariat, because it secures the position of the elite (those who don't have to obey "the law" made by the elite). However, this also makes the Spectacle more unstable (which is why sometimes they have to promote UMC interests against the lower classes - divide and conquer). Ultimately this instability is the thin wedge that we have to pin our hopes on. This is why exposing, mocking, analysing and denying the reality of the Spectacle* is our best tactic.
By the way, this mechanism is also fractal. There are elites within elites, untouchables among the untouchables.
Part II will deal with why the Government is a special factor in this mechanism, and why liberty is the ultimate political goal.
