The only statistics I ever see cited are those of the American Society of Civil Engineers, an interest group with a vested interest in increased infrastructure funding. I'm not hostile to the idea that we should spend more on maintenance, but I agree that we need some data from a less obviously compromised source. And that is setting aside the problem that increased funding has self-evidently not resulted in better quality of infrastructure. Kickbacks and corruption are rampant in that sector, a fact made clear recently in my hometown and county, which has seen a raft of corruption indictments and convictions related to public works projects over the last few years.
