I'd say that anyone that has 2-3 in their house means that they are solid financially and well off, atleast at the reasonably high end of the middle class (which is rich enough by my standards). Pretty much your average person can buy 2 or 3 if they tried to, but probably wouldn't want to, and those who do buy extra are indulging themselves (ie. rich at that point).
