Why?

Why do apartments and condos have almost no indoor lighting? I do not understand why. Almost every apartment or condo I have lived in has been this way. We end up with 37 lamps floating around the house, and the kids pull them over, and knock them over on themselves. That's going to be one of the important criteria when I buy a house. It must have lights in the rooms! Okay bizarre rambling rant over now, go back to your regularly scheduled programs. :-)
