Here's another tax question: Which worker receives the higher pay: a worker on a road construction project moving dirt with a shovel or a worker moving dirt atop a giant earthmover? If you said the guy on the earthmover, go to the head of the class. But why? It's not because he's unionized or that employers just love earthmover operators. It's because having more capital (tools) makes him more productive and therefore earn higher wages.
You might wonder how congressmen can get away with taxes and other measures that reduce our prosperity potential. Part of the answer is the anti-business climate promoted in academia and the news media. The more important reason is that prosperity foregone is invisible. In other words, we can never tell how much richer we would have been without today's level of congressional interference in our lives and therefore don't fight it as much as we should.
