Mongolian Tax

As some of you know, I spent 5 months in Ulaanbaatar, Mongolia.  While I was there, I learned something very interesting about the Mongolian tax code.  It is a 20% flat tax.  No exemptions.  No subsidies. No fine print.  And no H&R block offices anywhere.  Is the Mongolian tax code far more sensible than its U.S. counterpart? (Discuss amongst yourselves.)
