Time to go and acquire necessary food stuff is not a luxury in any reasonable framing. What is the alternative, eating drive-thru every day or having Instacart deliver overpriced groceries?
I believe eating food from street vendors was the usual way for paupers until quite recently. Recall that it was common to rent a bed for a few hours and share it with someone who worked different shifts.
Indeed. And I say this as Costco member. There are lot of factors that make Costco memberships work. And a lot of people won't be able to make much benefit out of Costco membership.
I say this as someone who admires their business model and how they treat customers & employees: your typical Costco experience is drive to the suburbs, spend $500 and load up your car with nice to have food products and discretionary purchases. Poorer people cannot do any of these things.
They don't require everyone to own a car. At the very least, they can run an efficient delivery service. And there's got to be a way to make a 3 hour rental or single taxi drive once a month much cheaper than owning a car.
It really is a luxury that a ton of people can't afford.
