Trump basically ran on a populist "politicians suck" message, and people liked it because... people don't like politicians or their bullshit. Everything he said felt good, and the people arguing against him were annoying as fuck. Trump didn't win as much as the left lost.
Now, he is learning why things are the way the system crapped them out, and is basically adjusting his administration accept those. I'm not surprised -
actually, I'm quite relieved, because he could be doing far more foolish things like keeping his promises - but anyone supporting his campaign should be kinda disappointed with how little he is challenging the system. He's literally saying that he actually talked about Chinese history with Korea for 10 minutes and now he understands China's position and is now totally cool with it. Like, no shit, do that before you make campaign promises about it.
EDIT
Mr Trump's last campaign ad depicted Janet Yellen, head of the Federal Reserve, as a member of a shadowy globalist cabal "who control the levers of power in Washington".
On Wednesday, he told the Wall Street Journal he "respects" the US central bank chief.
He also indicated he might consider reappointing her next year, saying she would not be "toast".
Mr Trump was once highly critical of the Fed, saying its low interest rate policy had hurt savers. Now he says he likes "a low-interest rate policy"
Way to drain the swamp. Your supporters who wanted the Fed gone must be ecstatic. Who am I kidding, half of them probably are for some reason.
