Kevin Drum writes:
One way or another, there’s really no way for the economy to grow strongly and consistently unless middle-class consumers spend more, and they can’t spend more unless they make more. This was masked for a few years by the dotcom bubble, followed by the housing bubble, all propped on top of a continuing increase in consumer debt. None of those things are sustainable, though. The only sustainable source of consistent growth is rising median wages. The rich just don’t spend enough all by themselves.
This is a bit perplexing. Wages rise because of economic growth and productivity. It is not the other way around. Similarly, Paul Krugman chimes in:
This is a widely held view, and I’m as much in favor of a strong middle class as anyone. Nonetheless, I’d say that in terms of strict economics it’s wrong. There’s no obvious reason why consumer demand can’t be sustained by the spending of the upper class — $200 dinners and luxury hotels create jobs, the same way that fast food dinners and Motel 6s do.
