How would infrastructure help a so-called civilized society if we were to turn our backs on minimum decency, especially for the elderly, disabled and others shown to be untrainable? Why not add up the trillions squandered on the War on Drugs prison-industrial complex and trillions wasted in Iraq, whom had nothing to do with 9/11?

There aren't enough jobs because there is an oversupply of productive capability (population is what it is) with fewer people combined with a (currently) corrupt US govt, resulting in extreme capital concentration by a few. Extreme inequality set the conditions for Trump, Brexit and the French Revolution. Balance is needed, or upheaval becomes increasingly probable.

Grass roots gotta get back the political process and clean organized labor is what has always worked (though paid usually in blood.)
