I am not condoning bullying but real bullying happens to those on the bottom of the ladder , factory workers, retail staff, cleaners etc where it can be vicious.
Bullshit
Absolute bullshit 
Bullying can occur at any level and in many different forms. It's still "real" 

I worked for a bully when I was an Account Manager, so a fairly senior and well paid level. Unfortunately the levels above him were also bullies, so there was little to be done (except leave - but at the time, I was the sole salary earner, so couldn't
Even so, dh and I decided after the break at Christmas one year that I was going to leave anyway, with no job to go to, as I was getting a new boss who's been recruited by the bully. Fortunately she was lovely and knew how to deal with the bully as her own father was a bully, so she'd reflected his behaviour at interview to get the job and I was able to thole the job for a couple more years before we were all made redundant anyway).
A colleague of mine went off ill with the stress of working for him - and I was expected to cover her accounts as well as my own. It was apparently my fault that I then found it difficult to do the double job properly
. When she then resigned (with a pay off), all that HR was interested in was that she wasn't going to go after the company for constructive dismissal.
Not surprisingly, I also went off ill with stress shortly after that - but my new boss (between me and the bully) was able to shield me from enough of his behaviour to cope with going back.
We used to dread team meetings, where he would attack someone (you never knew who would be the target that month) and demean and belittle them. And yes, it could be vicious.
I used to feel sick every Monday morning at the thought of going back into the office 
Outwith work, I've no doubt he was a charming man
Yet the boss before him (who I still consider a friend) was tough but fair - and as a result, got a lot more out of the people who worked for him.
