I guess I was inferring a counter argument to "the middle class is declining" which goes something like "the middle class is changing and not the same types of people now that it was then." Young people studying longer, settling down later, more immigration, etc. I went on a quest to find the numbers years ago and those were the conclusions I came back with. The numbers are messy.
