That's not always true, Cyber. Republicans have stopped talking about the deficit for some reason and the Tea Party is strangely silent.
In serious news, I agree that people are woefully uninformed about debt, deficit and so on. I feel that we are currently paying for infrastructure with our deficit which is ok by me. That said, we can probably afford to hike taxes a little bit and improve our services, ie. INVEST in our services.
We aren't paying for infrastructure, we borrow to build it all we do is carry the interest, we aren't actually "paying" for anything.
It's the same as me buying a car on a personal line of credit and never doing more than paying interest on the balance. One day the car is worth nothing but I still owe the same amount of money for it.
