I give Wall Street a big share of the blame for our current situation. Investors sent a messsage that they (we) would risk our money on any company that might be the Next Big Thing. Didn't matter whether that company had a product, profits, or reasonalbe cost/earnings. Nobody wanted to miss the next Xerox. So, hungry investors pushed up the price of ridiculously overpriced stocks, and expected those prices to keep on going up forever. Companies that wanted to attract investors' money saw that they had to "grow" as fast as Amazon.com, so they did so by acquiring whatever was for sale. Their real profits didn't grow, but the bottom line got bigger. When they ran out of companies to buy, they invented new accounting tricks to keep the illusion alive. A lot of CEOs got rich on the inflated stocks, but they were just along for the ride.
Investor's greed fueled the boom, now the bubble has burst, and those same investors are looking for someone to blame.
