Its about money and who's on the gravy train and fighting to elect republicans to keep it that way.
The proof they don't want you to know and will never talk about, but Bernie will!
Pay special attention to the part about The Wealth Distribution.
The Wealth Distribution
In the United States, wealth is highly concentrated in relatively few hands. As of 2013, the top 1% of households (the upper class) owned 36.7% of all privately held wealth, and the next 19% (the managerial, professional, and small business stratum) had 52.2%, which means that just 20% of the people owned a remarkable 89%, leaving only 11% of the wealth for the bottom 80% (wage and salary workers). In terms of financial wealth (total net worth minus the value of one's home), the top 1% of households had an even greater share: 42.8%. Table 2 and Figure 1 present further details, drawn from the careful work of economist Edward N. Wolff at New York University (2017).
