Okay. We have all this polarization happening, but what do you think of political evolution?> Do you see where it's headed?

Already happening, corporations are drawing in all time profits, while the buying power and hence standard of living for most Americans erodes. This will probably continue for a while until the social backlash gets strong enough to insist on reform. The corporations won't like it, but most of them still need to partake in the US economy. They'll compensate with increasing levels of automation. From there it's anyone's guess what happens. Will we begin taxing automated labor? Will we nationalize industries? Will we just accept an exceedingly shrinking job pool and expanding unemployment? What will the disenfranchised do?

One possibility, an increasing portion of Americans leave the country to work in second and third world nations that still need technical labor. This will lead to a sort of, "Americans are taking our jobs" dynamic. The result will be good for foreign economies, there might even be enclaves of American workers in some places. But an emigration based US would exacerbate economic inequality problems. With the employable poor working in other nations, it leaves the Haves and Have-Nots more pronounced.
