Nah, people honestly misunderstand it.

A friend of mine (U.K. but similar system) called me a few years ago because she knew I earned more than her so I was bound to have experience with this.

She was about to get a raise, and she was concerned that because the raise was just enough to bump her to the next bracket, the increase in taxes might reduce her take home pay.

I'm not sure how social programs work in the UK, but getting a raise in America can make you loose money since you won't have access to certain social programs.
