I think the real lesson is that the left and elites have long worked to restrain and throttle the economy so they could control the masses by handing out government benefits, and so the elites could benefit from lower wages.
Elitist control of government, and the resulting sell out of regular working folks, is being exposed by Trump. It verifies the accuracy of this quote:
“The comfort of the rich depends upon and abundant supply of the poor.” - Voltaire
Rich elites have learned to manipulate that equation through control of government and its policies. I don’t at all begrudge wealth honestly gained. I do bear resentment against those who step on others to gain their wealth. That is ill gotten gain.
