These days, it's very easy to convince voters that large public amenities—like sewers, highways, canals, and bridges that are meant to benefit everyone—need to be run by the government. Politicians have successfully argued that private companies, which are motivated solely by profit, would exploit the public at the earliest opportunity.
The evidence supporting these claims is largely emotional. What is far more certain is that the government's monopoly control of public projects and services almost always leads to inefficiency, corruption, graft, and decay.
