0) people like donald trump write trade treaties like nafta.
1) nafta allows a us factory to move from arizona to mexico, where it can pay workers a third of the price.
2) the workers at that factory lose their job.
3) the factory blows up the local economy in that region of mexico, forcing the locals into poverty.
4) that sets off a chain reaction of migration that pushes people out of mexico and into the united states, partially because
5) sub minimum wage pay in arizona is still more lucrative than work in mexico.
6) this benefits producers that create products for export but it reduces the pool of possible labour opportunities in arizona, creating structural unemployment levels.
7) what low education white arizonans are able to physically see and intuitively understand is that illegal mexican immigrants have jobs and they don't.
8) donald trump (carefully avoiding neatly shaved mustaches) stands up and blames it all on zee mexicans, in an attempt to generate a political base and distract from his own guilt and responsibility. mass unemployment creates social unrest that needs to be controlled.
9) the media agrees, in an attempt to construct a subscription viewer/reader base and further control the social unrest.
10) low education white arizonans vote for donald trump, but they do not expect him to reverse the policies that set off the chain of reactions.
it's a bit of a stretch to suggest it was planned from the start. but power has a tendency to perpetuate itself by profiting from it's own crises.
