This is not rocket science although the Lying Left and their Keynesian Economics buddies try to make it so.
TAX CUTS ALWAYS directly benefit those who end up paying less taxes and indirectly benefits others through an improved economy.
The only entity that doesn’t benefit from tax cuts is the miserable government which illegal 80% portion needs to be dismantled anyway.
Even the fedgov can profit from a tax RATE cut since it expands economic activity and results in a tax REVENUE increase. Check the Reagan tax rate cuts, fedgov revenue almost doubled by his term end.
