Perhaps I should have used a broader term......government builds the infrastructure......and since "government" is an unproductive entity, and generates absolutely no funds by itself, all of that proposed "infrastructure" that you suggest has to be financed by.....the taxpayer.....
WHO builds road infrastructure? -- Depends on if it's federal, state, local, community roads, or private roads. If it's a subdivision, I think the developer pays for it. Highways are obviously federal (although I think the state does it with reimbursal), and state roads are obviously state. The ICC in Maryland that was recently built I think was private development. I know in my parents community which is pretty rural, the community association pays for them not to be dirt. In some places, Chamber of Commerce will do "facelifts" to existing areas. When I was in Atlanta, I think the city must have paid for all the roads.
WHO builds energy distribution systems? -- Depends. Usually it's a private company watched by a federal agency.
WHO builds "cities"? -- Depends. Can be a corporation (Flint, MI), or a small group of individuals (Las Vegas), or the government (Washington DC). Usually they just kind of spring up, if there happens to be good conditions for commerce.
Not at all.....I just spent the past two pages of this thread attempting to explain (in a nice manner) why the electric car will never be practical here in the US, except for very limited applications. From an engineering and physics perspective........America is not Europe (or even Canada), we have a mixture of social, cultural and historic reasons why we won't live all crammed in dense urban areas. Won't happen, if for no other reason than the core of virtually all of our cities are ghettos, in which no sane person would live without armed guards and an arsenal. Those of us who are older and have been a part of the flight to safer areas understand the mechanics of this.
So... basically, you applied the word "Obama" to everything I wrote in your mind, to "prove" that I somehow must think that the only reason the electric car hasn't worked is that Obama hasn't spent enough money on it? I just want to get this straight before we continue.
