It's totally horrible for me to say this but a deadly flu pandemic is needed for the health of our economy.If it comes to that, I prefer a French Revolution style class war. Fewer deaths, more gain for each death and in total, thus more efficient. Between 10 million deaths, no correlation between dying and deserving it, and chaos and no reason to believe in political progress, versus 200,000 deaths, a high correlation between dying and deserving it (i.e. higher death rates among the current elite) and the likely deposition of the corporate upper class, I know which one I'd pick.
I'm not sure I agree with your premise-- I don't think society ever needs traumatic death, and I wouldn't want the violent revolution or the flu pandemic-- but if it were true, there's a much better way of getting it, which is to rise up and depose the assholes running the world now.
I think the problem is related to what you are saying but much more prosaic. For the most part, humans are myopic and reactive, and the people who tend to rise in organizations (in peace time) are even more that way than the general population. They make shitty leaders, though, due to their lack of vision. The result is that, when there is progress, such people would rather cut costs (and involve fewer people) than do more. That, in a nutshell, is why Corporate America is so depressing: it's run by mindless cost-cutters, not leaders.
Couple this with the mean-spiritedness of the US society and you have long-term joblessness and, eventually, widespread, cancerous poverty of a kind not seen since the 1930s.
