Why does it have to come from somewhere other than the company? Employees get raises. Both merit and cost of living. We have a young woman whose salary has gone up by 150 a week in less than two years. She's that good and we recognized it right away, she was given a 50 dollar increase after her first 3 months. I didn't raise my prices to give her the raises.
Also, your idea that grocery stores are using automated checkouts because of minimum wage increases is nonsense to me. I read this week that the minimum wage when adjusted is now lower than in 1973. We haven't had a federal increase since 2009 I think, and that was a small increase. Yet the automation keeps coming. IMO it's not because companies can't afford the wages, it's because our culture has changed and to the detriment of the worker. I'm not an economist but the things you say don't make any common sense to me whatsoever. I think they're bullshit. If you want to know the truth. I think you talk a lot of bullshit, and others are fooled.
