US corporate tax rates are the highest among developed countries, however.  Capital gains are also taxed higher in the U.S. than most other OECD countries.<p>Perhaps it all balances out between lower personal and higher corporate; I don&#x27;t know.  But there are so many other factors involved--debt, military activity, outsourcing trends, health and fitness, weather--that one can&#x27;t realistically call out taxation as a major cause of macroeconomic trends.
