Lengthen the term to qualify for the lower long-term capital gains tax rate
Many (most?) companies now have shareholder value as their primary goal. Unfortunately, shareholders hold stocks for a much shorter period of time than they did in the past leading to short-term thinking on the part of management.
If we required that shareholders kept their shares for a longer period of time to qualify for the lower long-term capital gains tax rate, this would result in a longer term focus, healthier companies, and a healthier society.
