Both sides agree that lower rates and less double taxation will produce more growth (though they’ll disagree on how much growth) and both sides agree that a low-tax/faster-growth economy will produce more inequality (though they’ll disagree on whether the goal is to reduce inequality or reduce poverty).
Since I’m on the low-tax/faster-growth side of the debate, this is one of the reasons why I’m a big fan of tax competition and tax havens.
Simply stated, when politicians have to worry that jobs and investment can cross borders, they are less likely to impose higher tax rates and punitive levels of double taxation. Interestingly, even the statist bureaucrats at the Organization for Economic Cooperation and Development (who, ironically, get tax-free salaries) agree with me, writing that tax havens “may hamper the application of progressive tax rates.” They think that’s a bad thing, of course, but we both agree that tax competition means lower rates.
And look at what has happened to tax rates in the past few years. Now that politicians have undermined tax competition and weakened tax havens, tax rates are climbing. …
… [T]here is a very strong “economic purpose” and “economic justification” for tax havens and tax competition.
Simply stated, they curtail the greed of the political class.
