It's apparent that from Cary's reaction and those of many of the commenters so far, the issue isn't whether the guy's a miser---because who's a bigger miser, this dude or the CEO of more half the corporations in the world, who consume vicariously through consumers, living off the life and labour of others?---but that he reveals the obscene supplement to their comfortable Capitalist lives: the destitute poverty on which it depends for its existence. In other words, the boyfriend wins the Capitalist game of life (i.e. make lots of money), but not by the same rules as those criticizing him on the LW's behalf. What's worse is he seems to be at least as satisfied with his life as she does, but on radically different terms.
