Trump is just putting what's currently happening into words, it's not as if what he's saying is anything new it's just that people get pissed when something like this goes public. The United States has for a long time Cared only for itself, not that this is a bad thing but the problem is that it involves other's hardships for them to gain.

I guarantee that nothing major in the US will change except the smaller issues just to make it seem something is changing but the bigger picture remains the same. Changes evolving wage, medical insurance, etc. these are fairly simple problems when you look at the bigger picture but sadly everyone focuses on how changes personally benefits instead of the greater good.
