So you're going to try to say im stupid for saying that your premise that only government can build infrastructure by citing links showing private companies building infrastructure costing more?
You do realize that if your argument is correct and private individuals building infrastructure costs more than having the government build it, then you've just proven my point that private individuals and businesses can build infrastructure, right? You've destroyed your own argument and you dont even realize it.
Sometimes watching how people think is the most peculiar thing.
