It's tax cuts for EVERY TAX PAYER. Quit it with your spin.
No, it isn't, as has been demonstrated. And second you're assuming a silent "only". There is no "only."
Both Trump and Bush's tax cuts primarily
benefited the upper crust, and of that upper crust benefited the richest the most. Trump's in particular were designed to screw blue staters, who tend to live in denser and hence more expensive states, primarily around those hated blue cities; replace stuff like the mortgage and state tax deduction with an expanded personal deduction, and you generally harm people living in higher tax states and pay higher mortgages.
Who is that, primarily? Well, blue states. Blue states typically have higher state taxes. Red states have lower ones, typicall. Red states only get away with that because they are net takers via the federal tax and spend power.
And who is more likely to have an expensive mortgage? Someone living near/in a blue city.
It did jack to stimulate the economy. It would be moronic to expect otherwise. Nobody invests in building more widgets unless they can sell them, and if they can sell them they do it with or without a tax cut.
Between their policies, this all cost over ONE TRILLION A YEAR in the "best economy ever." Thanks to Trump's malevolence and incompetence, he will be handing Biden a FOUR TRILLION DOLLAR DEFICIT in one year.
You will all promptly start caring about deficits again. And forget personal responsibility. Why pay for what you get? Borrow against your children and grandchildren so you the upper crust can have tax cuts.
