The value of salt in ancient time was enormous.
At least 40% of the federal gasoline taxes are wasted on non-highway items of dubious general welfare. And 2.86 cents of the revenue is used to subsidize mass transit unused by all but a few large cities.
As an additional inequity, Virginia is a donor state. That means that Virginia, like most southern states, sends the government more in gasoline taxes than it receives in federal pork. We don’t even get to waste our own money! Most of the pork is sent to the Northeast and to states with more influential senators.
