As someone who has worked several food service and warehouse jobs over the past few years, it's definitely pretty bad and gets worse the older you go. Though a surprising amount of younger folks I worked with were genuine socialists or Bernie bros.
With a few exceptions, gen-X'rs and boomers were the most brainwashed coworkers. But I felt really bad for them cause I could see the pain in their eyes and how age was taking its toll on them. Unsurprisingly, management always exploited them the most (forced to work off the clock, skip lunch, etc).
