"When the debt gets paid then and we have savings, then we can talk about a lower schedule." That ain't how it works. Increased revenue won't be used to pay down debt, it will be spent. The more money you send to the government, the more they will spend. Historically, that's how it's always worked.
"After WWII taxes were the highest and the economy grew the most." Post WWII the US was the last man standing. We furnished the world with products and food. We never had our cities and factories bombed to rubble, so we enjoyed a temporary economic monopoly on the world economic stage. And while tax rates were high, because of all the loopholes actual taxes paid were not.
Today in the world we have to compete with countries that have much lower corporate rates than we do, will offer free land and subsidies for moving overseas, and allow US companies to avoid unions, worker rights, environmental regulations and insulate them from product liability. It is not a level playing field.
You talk about high tax rates after WWII. Back in the 50'S when I was a kid working class people paid just about zero income tax. Mostly because of the dependent deduction, and most families had several kids. The deduction for children hasn't risen much since then. And families are smaller. Today, with two parents working, the income brought in by working mothers just about pays the families taxes.
"If you cut spending, lay off government workers this is money not going into economy". BS.. that money goes into the economy no matter who spends it. However, if the citizen gets to keep the money, it will be spread further and on more consumer items than if the government spends it, often on wars and other non-productive uses.
