Sonya is right about the uber wealthy will just sail away and purchase as they always have. The "affluent masses" reads, to me, the upper groups of the middle class. Remember, the middle class makes up the bulk of society, NOT the uber wealthy. ANd I think the bulk of luxury goods has always been purchased by those that want "better, prettier, be part of the crowd, I deserve it, etc", not those that really have the money to say "oh, I'll take one of each style in every color. Have them sent to my home. Ta".
When I've been out shopping, I never, ever, ever see cash or checks. Always credit cards. Now, they may pay them off each month. They may be using debit cards. I don't know. But, considering the amount of consumer debt there is, the fact that we have the worst savings account rate in the western world and the "gotta have it NOW" mentality that is woven into every fiber of the US culture; I seriously doubt it.
Those "creative fincancing rates" for home start to adjust in the next year. You think it's bad now? Just wait; it's going to get MUCH worse. Much worse.
