Don't be confused by the small arguments. Look at the outcomes. The middle class has not gained any ground since the 1970s. Wealth concentration to the very top is highest since the gilded age. Economic advancement for poor and middle class is worse in the US compared to most advanced western countries. [check the Economist and Wall Street Journal on this]
Unemployment is very low as it was under Obama; some economists call it "full-employment" but wages have not advanced (adjusted for inflation in decades). Corporations are sitting on trillions of cash.
A slice of middle class will see marginally lower taxes that will expire, whereas the corporations breaks are permanent; same for very wealthy individuals, investors, pass-through, etc.
Taxes should be used to buy.. civilization and the good life. It's what you get for paying taxes. Not saying all taxes are good or as used prudently, but goodies cost money. Paying less taxes may seem good but not having health insurance, or pay high tuition rates, living in toxic environment, etc, cost you a lot more.
So, outcomes? Compared to major countries, people in the US are not as healthy, or educated, or relaxed (more stress due to weak social safety net, higher crime, etc), don't live as long, and don't have as many chances to opportunity. But they are freer, right?...
