any opinions ...
Roads are expensive.
They are not fully paid for by gas taxes, emissions taxes, license and registration fees.
In order for designated taxes to pay for roads, they'd all have to double or triple or more.
All municipal, county, state, and federal debt has some component that is being used for roads.
If you've ever paid any kind of tax (sales, property, income, etc.) some part of it goes towards road building and maintenance.
Everybody pays for roads.
Roads/land that become toll roads aren't "bought" by a private company.
They are leased from the government.
Off topic but I wonder if you believe having a title and warranty deed to your house makes you feel you actually own it, rather than just leasing it from the government.
Anyway, toll roads are generally better maintained with better quality materials.
IMO mostly because of the difference in goals.
Toll company: "The company has a lease for 80 years, guaranteed road monopoly. We want the cheapest materials, that will last the life of the lease, requiring the least amount of upkeep, which will always be increasing in price, thereby maximizing our long term profit."
Politician(s): "I want to remain in office. I want to be seen as doing something good for people and the community. I want the cheapest materials that will last the amount of time I'm in office, at least this election cycle. I want the people who put me here to be happy with me so will vote for me again, so less taxpayer money is to be used, generating more short term gratifying optics for me, that I'm saving them money, while giving them what they want, as long as I'm here."
Not to mention, cheaper/lower quality materials = more frequent upkeep = creating/keeping more jobs. Good for politicians.
More expensive/higher quality materials = less frequent upkeep = lower labor costs, fewer road crew labor union jobs. Good for profit.
More incentive for private companies to focus on higher initial investment for cheaper long term costs, to maximize long term profits, given a guaranteed minimum business operations lifespan.
More incentive for politicians to focus on lowering taxpayer costs at all times with less scope beyond the next election.
Other than that, gas tax, toll road, it's mostly just switching responsibility for a tax hike. Accounting gimmicks.
Increase government revenue stream via leased toll roads, toll company gets the blame for increasing wallet outflow.
Doesn't really matter.
At best roads become a little less fueled by additional debt.
Growth in debt isn't as much. No cut in debt or taxes just less growth.
