It has been repeated several times by PR that the cost of entry is there to specifically keep people out.  The insult she intended was obvious, but it was more than a simple insult; see past it to the fact she was being literal.  Apparently they don't want the patronage of those who don't understand it and/or can't afford it.

Edit:
I like that you've noted PR's fees.  Mircea Popescu is paying a considerable amount of money, monthly, for your education.  Please have a little respect.
