It have nothing to do with being rich. It got to do with how much resources we got. We got PLENTY PLENTY PLENTY of water around here! More than what we needed. PLUS we got plenty plenty plenty of land to have sewer treatment plant set up. So it is not a issue here.
Most apartment rent includes water, so it is not an issue of cost. The reason for this is that the cost of supply the water is So So So cheap here. I know some areas in America, isn't as cheap as where I am. I pay average of 20 dollars a month, that includes sewer bill!
In addition to this, I DO sweat alot, and I hate the smell of sweat! If I don't shower more than 24 hours I STINK!!! No thanks!
