We've already paid for these highways, we've already paid for the upkeep of these highways, yet politicians want to promise more benefits to unions, come up with ‘living wages’ that are far beyond the median wages in the areas where construction occurs, and they happen to already have run out of our money to do all this with, so the obvious answer is - more of our money to run out of!
How about a use tax for public transportation? Only counts against the tax credits and refunds.
Ingrate ;-)
