Wrong. It's not a football match. There's no upper limit. If some needs are fulfilled, new ones (that used to be unimportant) appear. No enough cars for everyone, you produce cars. If the demand is fulfilled, you produce personal planes, etc. ad infinitum. Wrist watches were once unaccessable and kind of unnecessary for the majority, too. Just like stockings and other things that were once considered luxurous. EVeryone will find their niche.
