But he's not president.
Many Republicans believe lowering taxes inevitably increases economic growth.
There's no evidence that it reliably occurs. Indeed, there's plenty of evidence which refutes it. Take the Bush years, for example. Successive tax reductions produced little if any growth and ended with a crash. The period Republicans like to cite is the Reagan presidency, but this is better explained by interest rate changes resulting in a normal recovery from a recession.
Of course, this is the problem with the GoP on all sorts of issues. Climate change is another victim: the climate can't be changing as a result of carbon emissions because cheap energy funding capitalist enterprise is an economic good. It works backwards.
They don't care about the evidence. It's the theory that counts. For some reason, people on the right are willing to accept this state of affairs. I don't understand it, because the Reagan-Thatcher administrations were experimental but also scientifically inclined.
