Actually you're underthinking it. In this housing market, there is not enough ground chuck to go around for the number of buyers. Therefore the steak in unaffordable for many people. Same with housing. There is not enough on the market for the number of people with less income. Think it through and you'll see what they're talking about. Sure, there will be enough people to buy all that steak, but the converse is not true: There isn't enough steak for those who want to eat.
