Isn't socialist revolution ultimately inevitable?

No, the new system is clever. It is three-tiered. There are oppressors, and then two cles of economically oppressed peoples; those that spend their life working for the rich and those that don't. Us workers (the compent among the oppressed, those that would usually spark unrest and revolution) are perfectly willing to trade our lives for big screen TVs and 40-year mortgages on trailers - just because we have it better than lazy uncle JimBob.
