My point was that when corporations start buying up roads and whatnot, they will raise prices to extravangant levels and cross-country travel will become a luxury if you bow to taking their exhorbitant highways or a vacation of tedium if you can't take I-40 from Memphis to Los Angeles all the way.
Then the current government entities should not be selling the roads. Vote their asses out.
Besides, I see no indication that most highways are being sold. Toll roads were typically setup to build highways where there was a very specific group that needed the highway and federal funds would not be provided. Your example of I-80 in Indiana fits that picture - it was built mainly to satisfy people commuting into Chicago from bedroom communities. I-94 and I-70 was built by the feds, and they satisfy most needs for travelling through Indiana west to east or east to west. The toll road was built as a convenience, and convenience always costs extra.
Of course, you can make the case that taking the backroads results in a more fulfilling experience since you actually see America as you go, but what if the point of your trip is that you want to get to certain points QUICKLY? The point is that your choices, nay, your freedom is now limited.
I don't see anywhere in the Constitution where your right to travel across the country on a high speed, limited access road is guaranteed.
When we, the citizens own the road then we can have direct control over the prices. We can call our congressman or whoever and complain and threaten to vote her ass out. But with a corporation, their help line is going to say, "we're sorry if you don't like the price, use the backroads." There is no recourse.
So, how is that complaining to the government working on the current issue of selling toll roads?
Besides, taking money away from a corporation
now is much more likely to get action than the threat of possibly voting against them some years down the road. After all, if no one rides on their toll road, they'll go out of business. Happened in Virginia already.
