I think one of the most important lessons we can learn and teach to others is the idea of the hidden aspects of economics. What I mean by this is the opportunity cost associated with taking action such as taxation. As with the broken window fallacy taxation is often times ignored in the realm of opportunity cost. A new tax on millionaires may appeal to a large portion of the public because it is what is seen, a tax that helps support a bill to provide jobs. What is not seen is the opportunity cost associated with the money that has been taxed. Might it itself been used to create a job? Or spur an invention or innovation that might create 10,000 jobs? Or be used to buy a new car that helps people currently employed? These are questions that are difficult to answer but should be asked.
