I think we're running into the consequences of the wealth gap. The majority at the bottom end of the economy are too poor to be able to sustain our high energy economy so there's a ripple of contraction running up the line. If there was more wealth at the bottom there'd be more spending and the economy would be growing. It's happening in China and America (more so in South America than in the US but Trump's politics of greed is putting the brakes on in the North as well). It's not just morally wrong to have a huge gap between rich and poor - it makes no sense politically or economically either.
