I doubt the tech office perks are taking employee money from other companies. Warehouse work wasn’t likely to ever be awash in cash to lavish on the workers because that’s coming straight out of the customers’ pockets; every other logistics company is competing on that basis and consumers are generally price-sensitive.

pretty sure "the underclass of unwashed workers whose businesses are not awash with cash and thus it's OK to treat them like wage slaves." existed long before computers were ever thought of

I don't think they're saying IT/computers are a root cause, but rather that they might be modern enablers of these power hierarchies.

I think "allowed the creation" rather implies it is the root cause.

Mm, yeah. You seem to be right.

did not mean it that way, but that i've never seen in the tech press someone noticing that e.g. walmart doesnt have massage rooms
