If high taxes are bad for the economy, explain the 1950s?

Simple. In the 50s practically everything sold in the US was manufactured in the US. There were plenty of jobs for everyone. Stuff was exported all over the world which brought lots of income. Then some geniuses decided the US would be better of with a service economy and practically all manufacturing was sent out to places all over the world. Now our main industry is switching money from one pocket to the other, somehow magically making it grow and the only people making it big are Banks and investment brokers. Try finding such a high tech item as a toaster that says "Made in USA" on the bottom. As soon as an American inventor comes up with something new it is shipped to China for manufacture.
