For the sake of argument and me giving him the benefit of doubt, let's say he was speaking of the collective, in that case it's true, the middle-class spend more total per yr than any other group. But he wasn't speaking in collective terms, he was speaking based on the individual.
It's basic math, a guy making $1 million dollars per yr, even though he may indeed save a large portion of his money, has more money to spend than a guy making $40K per yr.
