According to this graph, which I have shamelessly borrowed from Paul Krugman (who obtained his data from the Federal Reserve), the best years for income growth were those immediately following World War II. Those were the days that brought us the Middle Class and what used to be known as the American Dream. How we are supposed to sustain a consumption-based economy (read: multi-billion-dollar casinos) on dwindling income growth is a question for far wiser heads than mine.
