I'll focus on the initial part of your post to point out that you _cannot_ trivially avoid taxes for operating in the largest economy in the world while operating in the largest economy in the world. Sure it's possible under certain aspects (like Facebook et al. paying nearly zero under being "mutlinational" and even that relies on the will of the government to allow it) but that does not apply to the US stock market, does it? Unless someone knows something I don't I can't be convinced financial players would stop trading in the US because of taxes unless they are really, really abusive. Some evasion to other markets, perhaps, but how much "down" to developing nations are large funds willing to go? You can't just seamlessly move the entire thing elsewhere. No other country has the economy and international (military) presence. Do we all agree that makes a difference? I can't see this level of taxation changing things at all
