I have the same response to the ‘Fairy Tax” myself...
The difference is that I am laughing at your seeming terror that someone dpwn the block might choose to spend less money than you -- thus "avoiding" paying taxes on something through his economy; and ending up with a dollar or so more than you. THAT is funny.
By the way -- there is a great deal of difference between tax "avoidance" and tax "evasion".
