"I wonder how much money is too much or is it just a way of keeping score when you have more money than you know what to do with?"
Another part of it is the stock markets insistence on ridiculous valuations based on growth. Just look at how much a company's shares can fall when their massive annual profit declaration is less than the stock markets predicted humongous profits.
"We predict growth of 20%. OMG!!!! Growth was only 19.9%!! SELL, SELL, SELLLLLLLL!!!!!11!!1!one!1"
