One interesting aspect (theory?) of the US QE is that the banks couldn't find enough great ROI on that free money in the US so they put it in "emerging markets". This lending created a boom and great returns in emerging markets for a time. But those debts need to be paid, and as emerging market currencies fall in value in respect to the USD, they become more and more expensive to service which limits profitability and the ability to borrow more. There is also the notion that rate hikes will mean more options for parking money, and less reasons to lend it to emerging markets. So those markets are no longer emerging, and some are submerging.I heard quantitative easing is driving wealth inequality.
We got a rippin' mortgage through QE. Our bank offered us a stupid deal and we said "fuck off, it's too good to be true." Then our planner said "no, no - they have to give it to you or else they have to give it to mortgages in trouble and their chances are much higher they'll get their money back from you. Take the money." We went from a 30 year with 27 years left to a 15 year at the same payment. I calculated it's gonna save us $80k. Income inequality.
