OECD countries that collect under 20% of GDP in taxes grow GDP twice as fast as counties that collect over 40%. That’s not an accident.
Most of the post WW2 advantage was because the war wasn’t fought on US soil. We were the only developed country they wasn’t destroyed by it.
We had the transcontinental railroad before income taxes. Most of our top universities were founded before income taxes existed.
Also, it’s the government that’s eaten our future. The local and state government pension obligations are insane. There are massive funding gaps which don’t count as debt.
Our big 3 entitlements and interest in debt will consume every dollar of tax revenue by 2032.
The government has stolen our future by implementing fiscally irresponsible and unsustainable programs. It always starts the same way. Promise the people something amazing. Increase taxes so the revenue growth is more than the cost of the program. Use the initial surplus to fund existing budget gaps. Then dump it on the next generation when the inevitable happens and the program isn’t financially viable.
