I have no idea, and I could care less. Arizona was listed last week as the fastest growing state in the country, no doubt accomplished on the back of miles and miles of brand new free roads. The growth will pay for whatever debt increase there was, which was the point of doing it in the first place. How do you think companies grow? They borrow money, duh. Governments can and should do the same thing and for the same reason.
Growth brings money, and borrowing brings growth which pays off the debts. If Texans are too stupid to know that, then I'm glad I left there in 84.
Any Texan that buys the line that it would take a buck forty per gallon tax increase to fund roads is a few cards short of a full deck. And the fact you're trying to sell that line demonstrates other things.
As it stands, the gas tax is about the same in each state, except 25% of the gas tax in Texas goes to schools.
AZ directs its lottery money to roads. We don't. AZ is hiding the cost of roads from the taxpayer.
