Not really… Pizza Hut is hurting, just like Wal Mart is hurting. Their core demographic is poorer than they were, and their numbers are increasing. The income gap is increasing every year. It’s all about the dollar - in Pizza Hut’s case, even billion dollar companies can’t give the store away without incurring losses. Their customers demand ‘free’ food. In Wal Mart’s case, when the government restricts income to the poor, their business suffers.
People with money can be picky, as in choosing and trying new concepts or better products - that has never changed.
