Yes, it does predate Obama, but he had eight years to do something, and he did nothing. Even the failing NY Times admits that all Obama did was kick the problem down the road.

Trump is not making it worse. The problem has gotten worse because of the neglect of Obama and China.    You can't blame Trump for inheriting a bad situation that conventional approaches have failed to solve. The "experts" have failed, so its time to try something new.

Let Trump deal with it, he's doing just fine.
