Big companies don't care about anyone but their stockholders, they'll even take your water.
How about a large city without water? It won't be long before there's another drought in Georgia. Atlanta's water supply comes from Lake Lanier. The basin itself is a very small area...it has to rain practically right on top of the lake to replenish it. A large part of Atlanta is the 'hood, it's going to get ugly when that many ignorant people can't get water.
