Costco is the American version of communism, from the $1.50 hotdogs to the high employee satisfaction, to the drab industrial-scale warehouses, to the two-or-three items in each category available.
Costco gets at a core American value, but it's not communism. It's the DIY, bootstraps attitude that Americans love. You get a deal but you basically shop from a warehouse that was built for forklifts, not customers. The displays are just pallets with a price board set on top.
Costco does an amazing job of delivering a product (quality food and merchandise) without any of the additional frills that would lead to markups, like nice ambiance or displays. That is a huge deal for millions of Americans who are happy to shop on bare concrete floors if it means saving money.
You might do well to, like, read a Wikipedia page on communism or something. OTOH, Costco does treat its employees well, so maybe it is a worker's paradise? (But I'm pretty sure where the comparison stops. EDIT: sibling points out that Costco actually has shelves with stuff on them.)
