So someone on the edge of poverty, balancing two or three minimum wage jobs just to make ends meet, should be considered part of the same class as the CEO of Microsoft or Google? Hell most people on the Forbes list 'work' in at least some meaning of the word, even if many of them effectively work for themselves.
What about the trust fund kid working part time at an art gallery just because they like the scene and hanging out with artists? Same class?
And on the flip side, are pensioners, the unemployed, and people on permanent disability part of the same class as the dilettante children of billionaires?
