The modern liberals and the moderates are keen on suggesting that ideology creates closed minds and stunted viewpoints, so let's drop ideology and look at the potential effects caused by taxing the rich, especially the current push to tax companies that make overseas profits.
Asia, for the most part, is moving forward economically by implementing capitalist principles and making their economic environment friendly to business, even if their human rights record leaves a lot to be desired. Europe in reeling from years of statism and is loosening it's business mindset to focus more on economic growth and less on soaking the rich.
As the global economy heats up and as statism reaches its limits and threatens to collapse whole economies, the trend will likely be for countries that need wealth to continue attracting companies by loosening regulations and lowering taxes, as America heads in the direction of increased regulation and higher taxes on the producers of wealth.
At one time, the Keepers of the American State could say that businesses have no place to go in the world because America is the most secure nation and the friendliest toward businesses, so the government could charge their fees to American companies for the privilege of operating in such a grand business environment. The world has changed, and, as time goes on, it will change rapidly as Asia continues to grow and Europe gets its groove back. The global economy will offer options for corporations more attractive than America's offerings -- much lower overhead and less government intervention combine for an attractive alternative to America's rising cost of doing business and undereducated labor market.
This has nothing to do with ideology -- it has to do with economic and business reality.
