That's besides the point. Most young people today can't afford a house. So they take a mortgage loan to buy one, and surprisingly, houses tend to be priced just at the level of the loan an average person can get.

The situation is different from the TVs and computers and cars because those are not considered as important as your own house. Most people eventually have to move out, so they have to participate in the game. I believe we call it "inelastic demand".
