That's cool because it means you can actually do that if your manager is bad. In some countries there are no jobs so all you can do about having a bad manager is... nothing.
That is true in the US for a lot of people, and it was especially true during the recession. The fact that we've been in a situation where most skilled workers can easily job hop for that last 5 or so years is an aberration, not the norm! And frankly, we should probably take advantage of the situation while we still can.

Are you talking about workers in general, or software development in particular?
In software development, I don't remember a time in the last three decades where a skilled dev couldn't find other employment with relatively little trouble. Of course, in some periods it was easier than in others.
I was a dishwasher/line cook in my 20's, I could hop jobs on a dime. Got fired one Friday, and had a better paying job Monday and that was in 2008. I wasn't even that good.
