Economic populists ALWAYS play the xenophobia card in a recession and try to pass off the idea that autarky will solve everything and create full employment. 
No, Flat Earth unfair trade policy loving cheap
slave labor apologist corporate stooges like you ALWAYS accuse people of "xenophobia" so you can shut down the discussion and pretend that "globalism" will solve everything. But here's something you sanctimonious disingenuous globalists have failed to acknowledge:
The whole thing depended on the U.S. consumer!! You know, the consumer who has been seeing wages stagnate and good paying jobs being offshored and outsourced and insourced. While dipshits like Thomas Friedman told us everything would be fine because we'd "retrain" and "innovate". Why, we'd all be Internet millionaires!
Gee, didn't exactly work out that way, did it?

And now, because those dumb fat lazy xenophobic hateful benighted Amurkins can no longer charge the cheap crap from China and Bangladesh on Visa or their HELOCs, trade has pretty much come to a screeching halt. See, that's the problem with trade policies based on corporations trolling the world for the cheapest
slavesworkers and most lax labor and environmental standards. Eventually there's no one left who can actually buy anything.
If you still think protectionism is the answer, how about if my state imposes a 10% tariff on goods and services from your state, and vice versa? Do you think that reducing interstate commerce and making the 50 US states isolate themselves economically would improve everyone's economic situation? Because that's what you're suggesting, just on a larger scale.Aww, how cute. Maybe it had escaped your notice, lo these past two decades, but what many states (and many cities) are actually doing is trying to lure big companies with tax cuts, subsidies, and TIFs. Regions are trying to outdo each other in a race to the bottom that is bankrupting their governments and usually NOT providing as many good jobs as they promised to the local community. It functions in a similar way to the way globalism does, with companies packing up and leaving as soon as another state or city offers them a more generous tax break or subsidy. In some cases they end up leaving the U.S. altogether, for even greener grass in Mexico. But hey, it's all good because, as you globalists like to say: "Outsourcing is GOOD for the economy!"
Edit to add: Calling people Freepers is against the rules of this board.
