how they think it should be distributed"
...the capacity for feeling short-changed and ill-treated, even among some of the most materially-fortunate people ever to live on Earth (US' wealthy and near-wealthy). No doubt it's a primal human trait, but for various reasons (as explained here) the ever-polarizing distribution of wealth and income in America has allowed more people to feel bad about their own situation by looking at the handful who are stratospherically better off.

Eg: the top 20% of the US wealth distribution actually controls nearly 85% of total wealth; people think the top 20% controls under 60%; and they think it should control just over 30%
Similarly: people feel that the bottom 20% of the economic pyramid "should" have about 10% of the total pie; they think it actually has about 3% or 4%; in fact, its share appears to be too small to show up on the chart.
After the jump, another chart showing how these misperceptions break down among income groups. The de-middle-classing of America is a familiar story, but since it will be seen as one of the huge trends of this stage of history it deserves even more attention than it gets.
