Having grown up in Ireland and seeing the terrorist group leaders on both sides sue for peace not because they cared but because they could not longer recruit in a booming economy and they themselves had no firm pension plans. Politician pensions (which the UK has) seemed a good option.. Hard to get a young man to take up the gun when he sees a future for himself. Same thing happened in Colombia and would happen in Israel if they could be made to trust richer Arabs would have less children.
But... America is already very wealthy, no matter how much extra wealth is injected, that will be lifted back from the accounts of the lower orders (below say 0.01 percents). American people are from the world's perspective a very fat and hungry cuckoo, gone past the cute fluffy stage and looking too mean.
The rich won't give up the cream, the plebs are being disruptive and may need curbing. What are the rich going to permit?
