in a word yes....without the threat of the IRS throwing all of us in jail unless we comply with their thousands of regulations there would be no need to the tax accountants....corporate accountants would still be needed at least for publicly traded and multi-owner firms....but the small business man could avoid these high accounting fees every month, freeing up capitol for reinvestments, pay raises, business growth etc...the overall effect on the economy would be tremendous and there would be more than enough work for the displaced accountants....the displaced IRS workers - well, that may be another story -- perhaps some other form of extortion could be devised!
They would have to fight with the IT people over the choice subway gratings.
