The Fed manipulates the interest rates to either slow down or increase the growth of the economy.
Contrary to what you think they do not manipulate interest rates. You should read the Beige Book once in a while which is one source of the FOMC's decision making.
They don't let Trump's stupid tweets influence their decision making.
Oh but Trump went to Whartons LMFAO!
Despite the US president attesting to the fact he finished “top of his class” at Wharton business school of the University of Pennsylvania, his former professor college professor William T. Kelley had another view.
After Kelley’s death, Frank DiPrima a close friend of Kelley revealed that the professor felt the president was a fool.
“Professor Kelley told me 100 times over three decades that ‘Donald Trump was the dumbest goddamn student I ever had,'” DiPrima wrote for the Daily Kos.
