Perhaps you would like to expand on my delusion. Why can't 50 clerks do the job of the IRS? I'll give you a thousand auditors.
It is not the complexity of the code which makes the requirement for having thousands of tax collectors. It is the incentive to cheat the system. There will still be millions of people trying to avoid taxes and it will still take the watchful eye of an intrusive and abusive tax collection agency to collect 2 trillion in taxes. If you think having a few clerks sitting in Washington DC can do the job, you are delusional.
