@inthehands David Graber's "BS jobs" should be a high school textbook. Late Stage Capitalism is a religion, and his 2013 artivle was 95 theses nailed to its door.
Especially when you ponder the "real" jobs done entirely in support of BS: top floor of management consultants bringing in money, supported by IT, HR, accounts receivable, payroll, janitors, cafeteria staff, and their managers... And all the jobs with 2 hours of real work a week and 38 looking busy.
