Most people believe in government roads, and people hate, hate, HATE tolls, so your average private road WILL NEED to be subsidized.
people don't know that private roads would work. they've experience mostly gov toll roads with huge waits. in real capitalism you choose what road to take , what rules to follow and what level of traffic you want. time is money so if you could drive 100mph on practically no traffic(no accidents) then you'd make the toll for free on the time you save . people don't think and trust government . you think capitalism works as in the dollar tree, walmart , Amazon, smart phones, toyotas etc but won't work in roads, healthcare why? all are just products. plus we pay half our incomes in taxes to government . i think capitalism would do things cheaper and you come out ahead and you don't become slaves
