People are attacking Trump because of his jobs language/tariff talk. If you look at his tax reform, and if the his business tax proposals do pass, that will motivate companies to remain in the US and tariffs would therefore would not be proposed.
Now for Trump's trade deals, I have no clue what would happen. For me personally, I do not trust the Yahoos in DC to negotiate a deal that would be “fair” not to mention “free” (humor) to the people of the US? Why, because Obama is a rabid radical ideologue and he has placed many rabid left wingers in the government.
Honestly, me neither. Frankly my bet is that Trump doesn't either. What I do expect (imho) is that the next administration's policies will be a 'yuge' change for the better.
