2) Because that is what people will pay for them.

Guy I went to college with went to work for Evil Corporation "X", and
basically lived on the road for like ten years. Wasn't married, so

budget can offset salary & bonus with such purchases, and the
resulting value to them is higher than for those of us who don't.

That is why the Sky Mall magazine is like it is...
