Dock workers striking against automation is the most American thing I've ever heard. When your country has a social safety net, it prevents luddite bullshit like this.
They're basically right. Automation kills jobs. More profit goes to the corpos and not the workers. If we redistributed those extra profits (tax heavily and reinvest in social programs), losing your job wouldn't be a potentially life-destroying experience. We don't need to have jobs that can be automated, but until we use that excess profit to help people, workers literally can't afford to not do those jobs.
