The key should have been balancing the budget and initiating an infrastructure plan.
You can cut taxes in some areas (business taxes, which were causing problems with money staying overseas and corporate offices in America doing everything they could to also move overseas because of taxes), and increase them in other areas (drop caps to social security, lower SSN taxes per person, but overall improve SS financing with no caps... it would be a tax against the rich though), road tolls or gas taxes, etc... In order to balance the budget and add in Infrastructure...
But Trump and his Trumpublicans didn't want to do that. They wanted to line their pockets with as much tax cuts as they could get away with, and were perfectly fine with $1 Trillion dollar annual deficit spending. And that's what they did.
Greedy MF'ing ignorant morons.
Not balancing the budget and cutting taxes when the economy was already doing fine is a definite contributor to inflation.
