Why is a crowded bar good? Why are cities teaming with people good? Why are malls filled with people good? Why is a highway, empty, expensive, under utilized, payed for by wasted tax dollars good?
Another way of looking.
Don't build the highway, and people won't come. People will move to the cities. Or, jobs will move to the country.
Either way, why is a personal and business problem a public problem?
Well, of course we know. Government needs to have, or more usual today, create a problem where none exists in order to have more money flow through its hands.
