The prices for other staples won't rise that much with an increase in rich people. After housing, the next major expenses for many people will be transportation and food. Rich people aren't going to raise the cost of a bus ticket or gas. There will be fancy restaurants and high end grocery stores that cater to wealthier customers but a typical store can't just double the price of a loaf of bread without losing many of their customers.
