Does everyone have a shit boss?

Hi all, my boss has been making myself and my colleagues cry on and off for the last 2ish years. They seem to genuinely enjoy the power trip/gas lighting and just generally being rude. Multiple people have left the team and/or the company as a direct result and a few HR cases have previously been raised but there’s been no change. We’ve all confided in each other and talked about how we’ve lost confidence with many of us starting anti anxiety/depression meds. Is this just how it is in the corporate world? A few of us are looking for external work but are we just going to be walking into the same situation in another workplace?
