90% of people who want the government to "go after the rich" probably aren't thinking about the guy who runs the flower stand down on the corner (though 10% do want to send the capitalist running dog to a re-education camp, especially if he is not a protected minority) but he's the one the laws are going to be written to target because he can't afford to buy himself political exemptions.
And in the era of ‘Corporatism’, those at the top are buying political exemptions that pull the ladder out of the reach of the ambitous. That eliminates the competition necessary for a healthy economy.
For those who ‘gave away their wealth’, look at Detroit now. The ruins atests to the tragedy of the commons. When no one is required to create sustainable wealth but depends on the kindness of strangers to improve their conditions, eventually the vein runs dry.
Why work if there is no legacy to accompany your wealth? I plan to change the growth pattern of my family tree with fertile soil.
