For years I kept hearing from conservatives about how JFK cut taxes.
One day I decided to verify that claim for myself.
JFK did not cut taxes, LBJ did. Kennedy may have had ideas and proposals about tax cuts, but it was Lyndon Johnson who got them passed and signed into law.
I do not accept the premise behind your question - tax cuts good / tax hikes bad.
We live in a three dimensional universe where simplistic bimodal choices are generally for the feeble minded.
LBJs tax cuts were nothing like Reagan, Dumbya's, or Brownback's foolish budget-busting tax cuts for the rich. The were correcting what was clearly an outdated and stupid tax policy. Right through the Eisenhower era and into the early 1960s, we still had the World War 2 marginal tax rates in place which were intended to pay for a world war, and the defense of Democracy. By the early 1960s, a the WW2 legacy 90 percent marginal tax rate (or whatever it was) on high income brackets was ridiculous and unnecessary.
It is worth remembering that Obama cut taxes too in his first term. Wingnuts seem to forget that. Tax cuts policy never boils down to "do it Saint Reagan's way, or don't do it at all". LBJ's and Obama's tax cuts look prudent in hindsight and will never be remembered by history as the foolish supply side economics of Dumbya and Brownback.
