What motivates someone to go on the Bachelor?

I can't stop watching The Bachelor.  I know it's ridiculous.  I know it's not at all about finding true love.  It's stupid.  No one argues that point.  Yet I watch.  And I can't help pointing out obvious things.

There were six women on last night's episode and Brad had to choose four at the end.  I'm mid-way through the episode via my BFF, the DVR.  Chantal is crying her eyes out because she didn't get the rose on a group date.  Her feelings are hurt that he didn't pick her as his favorite out of the three.  Poor sweet girl.  The emotions are obviously real, but weren't they anticipated?  Surely she's seen the show before.  They start with like thirty women and only one makes it to the end.  Your odds going in are pretty bad.  And with Back Again Brad, they're even worse when you throw in his first set of 30 women who didn't make the cut. 

I suppose we all get ourselves into situations with a known emotional consequence.  I'll just never get why these women do it to themselves to publicly.  It sure can't be the shot at fame anymore since reality TV makes up such a large portion of airwaves these days.  These "stars" are a dime a dozen.  They can't *really* think it's likely they'll find love.  I suppose there's the experience.  I mean I just saw these women in Costa Rica and now Anguilla.  I'd love to go hang out at these locations.  In fact, watching tonight I had the thought, (insert whiney voice here) "I wanna go away with my husband!"  Though I, without doubt, wouldn't want to go on those trips with the strings of watching him mack on other woman while I watched attached.
