In Burlington we were very clear about what we wanted to build. We wanted to build a road system -- an electronic public road system. Cities build public roads to be available to everybody on a non-discriminatory basis.
Cities are perfectly comfortable offering a public bus service as well, or a garbage service, not to mention fire and police services. There is no problem when these services use the public roads they build, and in some cases like garbage disposal and bus service, cities actually charge a fee.

Hi,
Interesting discussion. I find the anti-government/libertarian argument disingeneous. With one side of the mouth, govt. is inefficient and ineffective. With the other side, government entry into the market will put the private sector out of business. Which is it? And why is it that our social contract is to gaurantee profit to the private sector vs. provide essential services to citizens? Also, an economic PhD who doesn't understand the difference between general obligation bonds and revenue bonds is a bit sad. Finally, seems like the logic taken to absurdum (beside that all roads are going to be built with private sector financing - which is obviously false and beyond silly) means we should close down all state universities, water treatment plants, damns, public power, airports, public hospitals, seaports, etc. and make laws such that it's illegal for the public sector to participate (remember, the public sector is incompetent.) If we did this I suspect those PhD degrees may not have been awarded to industry sock puppets as the private sector would never have allowed that to happen ;)
