FLU, bad analogy with cars (I’m not a car buff and I just buy whatever and forget about it). The point is was trying to make is that most Americans are just average with some families making more than others. Incomes fluctuate and households move up and down the income ladder over time.
There is such effect as substitution. People who previously only shopped at department stores are now choosing Target and Costco because of prices. That consumer phenomenon is well documented.
As house prices go down people will substitute one neighborhood for another. Not everyone wants to move up. FLU, you may never live in Chula Vista at any price, but plenty of others who see the good deals will buy.
FLU, from your previous posts on cars, I can figure you would never buy a Hyundai. How do you figure the brand is successful in America? Someone is buying.
