I wonder what this means, though. Give me a sec, don't assume that I'm just blindly attacking. From what I've heard/read, the very top of the economic ladder is doing ridiculously well, with near-exponential growth in their worth, while the majority is actually losing ground. If the very top saw a huge growth in their value, while most of the rest of us remained stagnant or saw a mild decline, wouldn't that account for this statistic you posted? If so, wouldn't that actually be a sign of an unsustainable economy, and not a strong one?
