Michael Mandel notes in this post that among recent college grads who are employed, the greatest number have government jobs. They may produce little or no value; what they do may actually impede the production of value by others — but at least they have what they probably consider “good” jobs.
Another large category is the hospitality industry. Some 33,000 more college grads are working in hotels and restaurants. Their jobs probably don’t pay well and could be done by most high-school grads, but at least they are producing value.
