Right now, about 48 per cent of all US citizens pay no income tax. Most of the income tax collected comes from those that actually work. We have a whole sub culture of people that live off of the social welfare system and contribute nothing. The free ride has to come to an end.
As for schools, they are financed by the local school boards which rely upon a property tax. Roadways are state and county responsibilities paid for by local taxes and federal fuel taxes. Interstate highways are federal responsibilities coupled with local and state governments. The financing varies depending upon the project.
I favor tariffs. If someone wants to buy a fancy European or Asian automobile, they should be prepared to pay a lot more for it than a US made vehicle. Prior to the income tax, our nation's government was financed by tariffs. We can go back to that system.
We need to put our own people back to work. We need to accumulate the capital to re industrialize our nation.
As for the military, it seems as if the current administration wants to gut our forces. South Korea, Taiwan, Philippines and Japan are going to be pretty much on their own. Europe can defend itself if they have to. As we walk away from peace keeping, I suspect the Chinese will fill the void.
Sorry about the Ukraine, but they will get nothing from the US under this administration. It kind of reminds me of Czechoslovakia when the Nazis took the Sudetenland. "We will have peace in our time."
