How come work is so hard to find?

I was diagnosed with a tumor last Febuary and the company I worked for had to let me go due to medical reasons (Their insurance would not cover me) and recently was ok'ed to go back to work but, the financial crisis has put a damper on this venture and my old company has cut employees by 50%, What a bummer!:( I was feeling it was only happenig to me, then I started looking around, man! There sure are a lot out of work! I am just wondering, is this going to last forever? How come the big corporate honchos get canned for cheating and get giant severence packages? Is America gong to be in a depression? Days to come will only tell...as we move on into 2009 we will discuss the state of our troubles whether it be personal or public. I just wanted to know why we are in this sistuationb that so many are in.
