Liberals get tons of money from Wall St. In fact, Wall St. is a Democrat stronghold. Typical: Hillary Clinton’s Lucrative Goldman Sachs Speaking Gigs.
Those on the inside know that, when Dems talk class warfare, they are always winking at the bankers and at the ultra-wealthy, and hoodwinking naive populist voters. (I have nothing against the bankers. They are necessary for almost everything, but it would be fine with me if their politics were more balanced.)
