Finally someone states the obvious. Find a way to globally tax all this profit. Take that tax money and use it to create free education, health care and much earlier social security. Devote tax money to public transit, research institutes, recreation. In short realize that all this capital growth should be used for something good.

Good luck with that "global" tax on financial transactions; there are numerous markets in second-tier countries which see this as an excellent competitive advantage, and those countries are motivated to resist pressure to implement the tax due to past histories of humiliation and exploitation by developed countries. The wealthy have a much higher ability to rearrange their lives and businesses to avoid taxes than average people, just ask Eduardo Saverin. As a practical proposal, taxing the wealthy is likely to result in a much less significant result than you would expect.

I don't think this is true. Will stock trading move to senegal because the NYSE has a per-trade tax? Will the rich move to chile because they're taxed less there? Wealthy people still have to live inside the system, they ony escape heavier taxation because they're allowed to.

You could tax energy instead of labor.
