There was always going to be an increased initial deficit to his tax plan, I was concerned by it back then, but with successive governments both republican and democrat running up huge debts and deficits, the action represented an opportunity to try something else, but it was always dependent on growing the economy and encouraging manufacturing and businesses back to the US from China and other countries.
Really needed at least another term without a pandemic and and economic crash to see if it could turn anything around. I think reversing the taxes now in this current economic environment if Biden wins would be economic suicide, one of the reasons why I hope he doesn't. Trump might be morally corrupt, but Democrats don't understand economics, he's whats needed now with the economy on its knees and China on the rise.
