Taxes are already pretty massive; there is only so much you can take without consequences.

US taxes (state, federal, and local) are approaching 30 cents on every dollar, and that is with the Fed spending ~135% of revenues each year.

You might point out that many Europeans have higher taxes, and they do. However, they also have healthcare and generous national pensions. Americans have to pay for those after taxes. This makes it hard to freeze services and raise taxes.

The US has to get more efficient.
