> 1. This doesn't make any sense. The easiest way for the government to impose more taxes is to raise the percentages on the taxes they already collect. Private filing has nothing to do with it.
To raise the percentage rates, politicians have to vote to raise those rates. Private filing means that everyone is very aware of how much they’re paying in taxes. It’s not just an invoice they receive listing how much was withheld. They have to recalculate it. That makes them much more sensitive about voting for politicians who vote for higher taxes.
> 2. Americans don't have the lowest tax rates in the developed world. Mexico, Ireland, Chile, Turkey, and South Korea all have lower tax rates[1].
I don’t think people would consider Chile and Mexico to be developed countries. You’re right that Ireland and South Korea are lower (depending on the year, Ireland cut taxes significantly recently). But they’re together with the US in the bottom band.
> And in some cases the governments provide more services with less money because they're not spending half their budget on occupying other countries.
I think it’s true that other countries do more with less. But it has little to do with the military budget. US government spending as a percentage of GDP is 38%, meaning all levels of US government spend $7.3 trillion annually. The military budget is just 10% of that, or 3.2% of GDP. That’s high compared to Europe, but not a big difference compared to overall government spending. The US military budget is proportionally where the U.K. and France’s was in the late 1980s, back when those countries had robust welfare states: https://worthwhile.typepad.com/.a/6a00d83451688169e2022ad3a0...
If the United States cut its military budget to the same proportional level as France, we’d have an extra $175 billion for other things. That’s not nothing, but to put that into perspective, we spend $970 billion a year on education (5% of GDP). We spend $1.1 trillion on healthcare and welfare for poor people. Cutting our military budget to European levels wouldn’t revolutionize our budget.
