[Willie Green]

Why is it, do you think, that privately maintained infrastructure can make a profit but socially mainted infrastructure cannot?

Here are two privately maintained highways that went belly-up:
South Carolina toll road in rare Chapter 9 bankruptcy
California Privatized toll road goes bankrupt using taxpayer money

Pataki's privatization of Stewart International Airport also went bust and the Port Authority had to buy back the lease from the incompetent private operator.

[Mr. Lucky]

Gosh Willie, the Indiana Toll Road is privately operated, charges 40% less per car mile than the Pennsylvania Turnpike and makes a profit. Railroads make a profit, pipelines make a profit, electic companies make a profit, telephone companies make a profit.

There's nothing inherent in "infrastructure" which makes it unprofitable to own and operate. The incomptetence and corruption of public ownership are merely poor substitutes for the efficiencies and discipline of the private market.
