Trump may be right about H1Bs, but he's knee deep in corruptive patterns. The details will come out when those "old buddies" start doing their "former" businesses huge favors.
Well, you might be right, but it helps to cite evidence to your assertions.
Just because you used to work for Goldman in the past, does not mean you are a current and future supporter of Goldman.
Nor does it mean that you are a bad person.
Trump is hiring people that know how these companies work from the inside-out. Which is the exact type of person you need to be able to deal with these companies head-on.
So it works. Integrity and patriotism matter of course. Diversifying investments prior to taking office would help reduce temptation.
