Here's data for you. After we pay for Social Security, Medicare, interest on our debt, and defense, we are already deficit spending. That means that every other thing the government spends money on is deficit spending. Mind you, this was at a time of economic prosperity. Bottom line: We have to eventually raise federal taxes. Nobody likes them. Nobody wants to. But we sorta have to.
Historically, it has been very difficult for the federal government to raise revenue exceeding about 17% of GDP. And at some point, increasing tax rates results in lower tax revenues because people find ways to avoid paying the tax. You're probably familiar with this concept, expressed in the Laffer Curve. At a tax rate of 0%, no revenue would be collected. But at a tax rate of 100%, there will also be no revenue collected, because nobody would work for anything that could be taxed at that rate.
So, while I agree that revenues
do need to increase, we can't squeeze blood from a turnip. The economy has to keep growing for us to get higher revenue, no matter what the top income tax rate is. And the higher the taxes, the less the economy grows, all other factors being equal.
And we're going to have to cut spending too. At some point, the debts have to be paid, and revenues of 17% of GDP cannot pay for the federal government spending of 21% of GDP, which is what it was in 2015, a reasonably prosperous, non-emergency year.
Bush 41 and the Democrat-controlled Congress made a deal ca. 1990--when the federal debt was about 1/3 of what it is now as a percentage of GDP--to raise taxes and cut spending. Bush signed off on the tax increases, which may have cost him the 1992 election, but the spending cuts were--in GOP eyes, anyway--less than what had been agreed upon.
Since then, it has been accepted wisdom within the Republican Party that Democrats cannot be trusted on a revenue-and-spending compromise. (And maybe the Democrats have some other lesson from that experience, I don't know.) That was back when there was much less polarization than there is now. It's hard now to see such a deal being passed, signed into law, and carried into completion.
