There are two types of customer service agents at US. Topped off senior agents, and minimum wage new hires. The majority of agents in the middle have left for greener pastures. You brought up flipping burgers at McDonalds. Which would you rather do for $8.00 per hour, flip burgers, mow grass, bag groceries, or work understaffed with unhappy customers screaming in your face. It's a turnstile door at US. Newhires don't last long, and then a new batch of victims is brought in. The senior agents feel trapped, starting over somewhere else most of the time is for less money, even with my Bachelors degree from 25 years ago. So if you want competent agents, who will stay and learn the job, you need to beat McDonalds on the starting pay.
