I thought it something to do with mortgages and lax standards as China had a need to place 1.5 trillion dollars garnered in part by pegging to the dollar and erecting their trade barriers in their home market.
wall street found a way for a place for their money in crazy second mortgages thereby making big profits in the short run.
then when the obvious happened the fed switched out China's trillions into govt backed securities.
Overall, my observation is your government, special interest groups, and media have Americans in crisis mode all the time since 9/11. Canadians are more laid back about this and know whatever Trump will do we'll adapt and move forward. My life isn't going to change by any of this. Some might. What I'm thinking is enough Americans will lose part of their livelihood if protectionism takes hold, and you'll hear from them soon enough. Just like we're hearing from you about your medical premiums and deductibles now. You'd cry if you knew what I pay for me and my family, and none of us have had treatment meaningfully delayed in our lifetime.
When I was younger, a huge chunk of my pay as a single guy went to taxes. This was because our federal debt was massive and getting bigger and interest rates were massive. If you are not careful, this is where the US is headed. Trump's tax cuts may look absurd a few years down the road if your federal bills are uncontrollable and the tax base shrinks ( due to aging and the quality of jobs ). You guys are kind of drifting towards that and betting on an economic expansion from huge spending. We'll see what happens. Might be alright, might not be. I doubt that cutting off international trade is part of the solution.
