Being famous is probably terrible

I suspect you're assuming that because a) you're not famous, b) you don't want to be.

People stay where they are because the pros outweigh the cons. You want to be admired by the thousands of people? Those paparazzis are annoying, but if this is what you have to do to remain admired? I'd trade that for such a goal.

With abusive relationships it's more complex, but the core is the same. You're persuaded to the idea that you aren't worthy of love, and when someone comes along that gives you that love, you admire them. Now, at least, there's some honey in the barrel of smut. Better than no honey at all. You stay because you perceive it as being loved, though it hardly ever is so. Leaving that one person who loves you is a terrifying thought because surely, nobody will love you afterwards... right?

Matt Damon has been quite eloquent about it when talking about his mother's job as a teacher and his as an actor:

A teacher wants to teach! Why else would you take a shitty salary and really long hours and do that job, unless you really love to do it?
