let me ask you this instead
how easily do you accumulate gold in wow without farming?
some people spend money as fast as (or faster than) they can get it
for those people, it doesn't matter how much they make, it won't ever be enough

on the other hand, $75 a month shouldn't be a big deal even if you're making only $15/hour
(unless you have a family or high maint gf)

i know someone who used to order pizza every weekend, now he only does it once a month.
that's $60+ right there, plus he's eating much healthier.
