The funny thing about Trump is that, he insists on his ideas for so long that, sometimes they do become right eventually.
Because if the rates were cut exactly when Trump wanted it to be cut, then it would have been not that great for the country, and yet, slowly, FED declined to cut the rates for so long that, now it's basically a must do thing, so right now Trump is right. He had some ideas like that, where if it was done the moment he wanted it, it would be horrible, but wait a few years and he becomes right eventually.
Not because he knows anything or can see the future or anything, because if you do EVERYTHING trump asks the moment he asks it? The nation would crash in a month. You just have to ask him what he thinks, wait 2 years, and then do whatever is good, and ignore whatever is bad.
