Well, I'm not talking about being in a tax haven necessarily. Just a simplified tax structure. No need for taxes on income and every other thing. Just taxes on what you buy new at a store. That alone would eliminate any tax loopholes, or tax avoidance strategies only available to the uber wealthy. It would avoid tax incentives for buying one technology over another, or one company/developer over another. It would also cut the IRS size down to almost nothing, as the only thing that would be needed is the staffing to manage the business reporting of sales taxes received and audit anything necessary. Hundreds of millions of tax returns for people and businesses would be eliminated. The overall taxes paid would still be about the same (unless you can get Congress to quit spending/printing money), but that's a different subject.
