In response to changes in the economy and the technology that supports it, companies were flattening their management hierarchies and eliminating entire layers of middle management. They couldn't support the overhead and they didn't need the oversight these managers typically provided. These people were especially vulnerable because they had been raised in a culture that equated a job at a big corporation with security and tacitly assumed that they'd be doing the same job, or climbing the corporate ladder, pretty much all of their working life. Not only were a lot of these people not prepared psychologically for what happened, they weren't prepared educationally or financially and the result was an enormous amount of pain and dislocation. Which still leaves the problem that not all lawyers, or CPAs or programmers are excellent and passionate about what they do.
Some people see that happening.
It's a truism that a jungle is teeming with life. What's especially interesting about a jungle is that almost all of that life is highly specialized. It's not just that there are a lot of trees, for example, but where a New England or European forest might have 30 species in a typical plot, a jungle will have 200 or more. You don't just have orchids living in the trees, you have species or orchids adapted to particular levels in the trees and to conditions like clearings alongside waterfalls. In nature, the richer an environment is, the more ecological niches it supports.
