propose a cash flow tax of 1% of all movements of money without exception, exemption, or exclusion.

A Cash Flow Tax would collect .5% from the transferor (the bank debit) and .5% from the transferee (the bank credit) on all transfers of money -- no exceptions, exemptions or loopholes. All government expenditures would be included. So would all charitable contributions and all religious contributions. Banks would collect the tax automatically and would be paid for collecting the tax by using the money for whatever time is appropriate. The full 1% would be collected at the time of transfers to or from a foreign country. There would be no tax returns, the entire internal revenue code would be repealed, investment speculation, especially currency speculation and commodity speculation, would be beneficially regulated by the tax. There is absolutely no downside to this flat tax.
