Usa employers did the math they fire most full-time employees and reduce staffing and only hire part-time workers walmart back in 2011-13 when I worked there only had 8-10 full time employees which were managers and even some department managers would only get 32 hours a week to avoid giving benefits or health insurance. Every one i knew who were full time worked there for 10 + years. Even if you increase minimum wage they will find ways to reduce costs in staffing so you really need to penalize companies
