which decisions of hers did you find irrational?

I recall her writing about a job requiring a belt, and spending $40 to buy one new. Without a mention of a thrift store.

As someone who lives on about $750/month [1], both the game and the book seemed not to notice major ways to save money like having a lot of housemates, commuting by bus, combining proteins, and thrift stores.

Being poor definitely sucks, but the book and game imply it is impossible, which it clearly is not.

[1] this doesn't include taxes and health insurance, which are deducted from my paycheque, but if I were making only $750/month I would have free health care from MA and negative taxes (EITC)
