The room of people who will control Trump
is the GOP Congress critters.
Yes the same party but most of them loathe him.
They will just carry on and do business as usual. viz, block whatever the president wants to do.
That's what Obama has faced these past 8 years. IMHO, it will be no different for Trump.
His economics policy is daft. It will see the USA go into default. Who will take over? The Chinese who have been buying whole rafts of the US Business world these past 10 years.
I fear that the next 4 (or god forbid 8) years will be hard on us all.
The mattress filled with gold is looking pretty good at the moment.
Unless the rest of the world says 'fuck you' to the US and gets on without them. Let him build a wall. It will only harm his voters in the long run.
