The series seems especially silent on the topic of money and purchasing. Does magic simply allow Brakebills students produce products that otherwise they'd have to purchase in the muggle economy? Or do they typically have some source of income with which to purchase things outside of Brakebills?
There are some examples in the series of magicians acquiring money. Julia once robbed an ATM using magic. Sheila found a box of money via quaeromancy (but she wasn't a Brakebills student.) Also, there was the episode where a gr oup of Brakebills students robbed a bank to acquire gold. But those seem like special cases, not "I need a few bucks to buy a cinnamon churro" money.
Meanwhile, students seem to consume quite a bit of alcohol and are occasionally shown eating food that wasn't mentioned to have been acquired via any magical means.
Basically, do Brakebills students participate in the muggle economy, and if so, how do they acquire money with which to make purchases?
