Abolish the IRS — and the Income Tax with It

The Internal Revenue Service has been caught engaging in political profiling while processing applications for tax-exempt status. In this case it was against organizations with “tea-party” or “patriot ” in their names and other right-wing groups. Next time it could be libertarian or left-wing antiwar and pro-civil-liberties groups. No dissenter can ever rest assured he is safe from the arbitrary power of the IRS.
Nothing will have been learned from this scandal if all that happens is the firing of some IRS administrators and the issuance of new guidelines on 501(c)(4) applications. That is not nearly enough.
