One nuance here is someone making $31,200 is barely getting by. It might only be .77% of their salary, but 50% of their annual savings. The difference between saving $500 and $750 is substantial. E.g. if you’re trying to put together 20k for a down payment, that could be a > 10 year difference in time it takes to get a house.
If you're living that close to using all your salary every month, there are probably better things you can do to save more than cancel Netflix. I think that's what the OP is trying to say.
Netflix is really good value for money. If you want to cancel something, cancel your cable.
