A business can’t afford to pay its workers more than they are worth to the business. From Jazz Shaw at hotair.com:

Back in early February, we looked at a story out of Long Beach, California where the City Council passed an ordinance requiring large, chain grocery stores to provide workers with an extra four dollars per hour as “hero pay” during the pandemic. That immediately resulted in two of the biggest Kroger stores in the area closing their doors permanently, putting hundreds of people out of work. At the time, I noted that a number of other large municipalities in the Golden State were either already drafting or considering similar legislation. But having seen what happened in Long Beach, they thankfully had sufficient warning not to make the same mistake.
Or so you would have thought. But as it turns out, you’d have been wrong. Los Angeles plunged ahead and passed the same type of law, only they upped the ante and made it five dollars per hour. Try not to faint from shock when I tell you that three more Kroger stores shut down in short order. If only someone could have somehow foreseen this and avoided all of these closures.
