Of course, complete income equality is a utopian fantasy. Everyone is endowed with different interests, skills and ability.
Communist/statist societies are, ironically, the most unequal of all. Ive seen it first-hand. Its income inequality is hidden, and is expressed as power and control over collective resources.
Absolutely...The only commodity that is provided on an equal basis to the hoi polloi of collectivist societies is misery.
