Real-wage Unemployment
Meet James. James lives in Michigan and he's worked as a delivery man in a pizza chain for over a year now. Although the wage is very low, he is satisfied with his job, because he thought he will never get a job after quitting highschool. James is diligent - he never gets late to his work and he never delays his delivery service. The company that's hiring him pays him $5 per hour, which is the minimum wage the government assigned. If he worked 8 hours a day, he could earn $40.
But one day, James gets a call from his boss, Tom. Tom says "I'm sorry, James, but we are not hiring you anymore". Baffled, James asked. "What?! Why? Did I do something wrong?" "No, but the government has increased the minimum wage. We have to pay you $8 per hour, and we can't afford that". James was angry and upset. He asked, "You really don't have to raise my wage, just let me work he here please." Tom, sighs and says "I'm sorry but we can't. That's illegal. We are cutting off some of the men we'd got, sorry. You don't have any family that you're responsible for. Find another job."
James got fired because the government raised the minimum wage. The company couldn't hire him anymore because hiring him would be "too expensive". Number of workers are the same, but the demand of the workers now fell, which led to unemployment.
