That's because the public sector doesn't build hardly anything anymore. They pay the private sector to build it. With little in the way of warranties, or so public perception goes. So then the public sector has to pay even more money to get stuff fixed, and contractors have little to no incentive to increase quality. Germany has warranties on roads. Their roads are supposed to be good. Italy isn't as good about warranties on public projects. Their road projects are supposed to be quagmires of corruption. The US? In the past, the practice had been for 1 year warranties on road projects, but following the example of countries like Germany, Spain, Denmark, Sweden, and Great Britain, federal officials have been trying to extend that out to 5 years for all federally funded road projects. New Mexico had a 20 year warranty on one project. (EDIT: I did some Googling, and found that some progress had been made, actually. My opinion on this was formed in the 90's, but there's new information now.)
