Revenue always rises, except in a recession. It rises because the GDP grows, and because of inflation. In other words, if inflation is 2%, and GDP growth (as reported "net") is 2.5%, then the actual GDP rose 4.5% in absolute terms. That growth is due to economic activity that is taxed. It happens every year outside of a recession when there is NOT a tax cut.
Thus, "But, at least individual income taxes collected did rise in fiscal 2018 due to tax cut" is completely wrong. If this is the basis on which you think Trump's tax cuts were genius, then I am relieved because you will no longer feel that way now.
As to your other point, let's start with whether the President should be able to use the Fed as a strategic tool for anything. The answer is no. The Fed should respond to the economy, not the president.
