The Economic Argument for More Tolls

Don't tell me that there's this huge productivity enhancing non-quotation mark, economic return on investment generated by the government building stuff that the private sector doesn't want to build. The government builds it and we've seen with the highways they're building it, but often in the wrong places. There is a public backlash whenever tolls make sense. But there's actually an economic argument for having more tolls than we currently have.
