The middle class is shrinking precisely because what it means to be "middle class" should reasonably grow with increases in productivity.
And it has. Every decile has considerably more stuff today than they did in 1980. More cars, bigger houses, more food, more medicine, and more education [1].
Jbooth is making the fallacy of measuring income in non-constant baskets of goods. His claim is that in 1980, median wages bought you 1 basket of goods, and in 2010, median wages still buys only 1 basket of goods. He is deliberately ignoring the fact that the basket in 2010 is bigger.
However, this isn't happening. And by many measures its decreasing (say health care, college education).
The same is true of medicine - we consume more drugs, visit the doctor more, and get more treatments. According to a quick google search, the % of the labor force producing health care has gone up considerably: http://www.doctorhousingbubble.com/wp-content/uploads/2009/1...
You might want to argue that consumption should have increased more, but it's nonsensical to argue that consumption has not increased significantly (as jbooth is).
[1] I don't like treating education as a consumption good, since it's primarily purpose is to gain credentials/skills so you can get a job.
