If you raise minimum wages, you raise minimum prices across the board. If Walmart paid more, prices would be higher. I have several neighbors who work at Walmart. They make between $13-$15.. one is the deli manager, another is manager of produce, and another is a sales manager or something over a clothing section.
Friend of my owns 3 Tim Horton's. The company sets the prices, he doesn't. He used to pay his managers $2/hr more than his regular workers, and his nights workers made $0.75/hr more than his day workers. When minimum wage went up, he couldn't adjust. His managers now make $0.50 more than a regular employee. He cut his personal pay from $60,000 to $50,000 a year. He's the business owner.. and makes $50,000 a year. That sucks.
