"The share of national income going to wages and salaries is at the lowest level since 1929 -- the year that kicked off the Great Depression. The share going to after-tax corporate profits, which heavily benefit wealthy Americans through increased dividends and capital gains, is at the highest level since 1929."

Distribution of Wealth in the US:
Pie ChartWealth distribution is even more skewed than income distribution: The wealthiest 20% own 85% of the wealth; The top 20% of earners get 60% of the income.
Rather than push for an income tax to redistribute income, it would be both fairer and more efficient to push for a wealth tax to redistribute the wealth, particularly 'natural' wealth that could be considered a common birthright. Taxing natural wealth does not discourage production, and hence does not discourage employment and suppress wages, as does taxing man-made wealth and capital.

Pie Chart. In short, don't confuse the capitalist with the landowner - the capitalist requires labor and must cooperate with it, the landowner does not. They are often the same entity acting in two roles, one beneficial, one parasitic.
