Why is it the employer's responsibility to provide a living wage?

[KUSA]

That's an irrelevant equivocation. And considering you've already told someone to go live behind a dumpster because their rent is too high, what do you care?

I actually do care but I like to play devil's advocate to stimulate the conversation.
And I only pointed out that the dumpster was an option if the current residence was not appealing.
