The Bachelor-Wreck

I've been watching stories on Swagbucks TV about Emily Manyard, better known as The Bachelorette.  Her engagement has ended after her fiance cheated on another woman.  That's the reason that I don't watch that show, or The Bachelor.  I know that many of those people don't make it to the altar.  If there was a higher chance of success for those hosts, I'd probably watch them.  Why do those people have to surround themselves with so many members of the opposite sex at one time, anyways?  Who do they think they are?  Austin Powers?
