The article is comparing 'college-educated other workers. Having a bachelor’s degree hardly makes one “rich” nowadays. In fact, it seems to be a union card for all but the most casual employment, while it used to mean entree to a much more rarefied tier of work.
But the article does spot a trend that I noticed some time ago: those that are employed full time are generally overworked, and putting in long hours. But their employers still aren’t hiring, and often seem to be willing even to pass up on business rather than taking the risk of hiring enough staff to handle the business. So you wind up with relatively few overworked employees and a great many unemployed.
