"Chicago School Economist Becker and Judge Posner blog that the majority of minimum wage earners are wives earning pin money, part-timers, retirees supplementing incomes, teenagers getting work experience (References svp). Raising minimum wage will hurt the "really" poor."
Well, it is probably true. No serious full time workers earn minimum wage, even supermarket cashiers earn about $10/hr on average. Those who earn the minimum wage are part-timers or students. Raising the minimum wage will decrease the number of minimum wage jobs available and hurt these people.
