Warren Buffet would agree with this along with many other super wealthy. Consumer driven markets are driven by demand for products. If the majority of consumers don't have the money to purchase products, demand stagnates and the entire economy suffers. Eventually it hits the wealthy also.
Being wealthy doesn't make you a sound economist. the societies with the most scewed distribution of wealth are precisely the ones where the government interferes the most. In other words, the they are ones where liberalism is in full control. Free enterprise created the middle class, not government control and confiscatory taxation.
The UNIONS and their members would like to have a word with YOU...THEY think that THEY created it as did their collusion with Government...Just sayin from what I read here in these pages...
