You all do know that recessions and such are cyclic things? Every few decades, you have a huge recession, and in between, you have a cycle of ups and downs.
What we have here is not as simple as pointing at one guy. We had the computer and internet hype, which backfired. That hype led to a corporate culture of "more more more", instead of long term planning. That led to corporate fraud. Most of that is a direct result of stock holders losing sight of what is important; the sky was the limit, and nobody gave a rat's arse about tomorrow, let along next year.
Then there's the lingering recession in Japan, the problems in Europe (Germany, France), and even problems in South-east Asia... South America is fucked up, as is Africa. All of those countries are not importing stuff from the US as they once were, which means less demand, and less production. Job losses are a logical result.
(Okay, I'll be honest: it was me. I'm the Jewish conspiracy, the secret world government, and I like to see people lose their jobs. Blame me.
