What Nix said is pretty much how I feel. There's nothing inherently wrong with "hard lefty laborites" who are in a wealthy or comfortable position in life, but there is if their consumption habits tend to overtly conflict with their beliefs, or tend to define them as a person. This:
Especially those who want to abolish things like private schools yet send their children there. That's inexcusable.
Is basically what I mean by that. Wealth and socialist beliefs are not incompatible things, inherently. Consistency is all that matters.
