I have always questioned the different standards for men and women participants. Why is it that the bar is set so low for the heroette?
Our heros must not only be buff dudes, but be zillionairs, successful businessmen or athletes (no matter how pseudo), charming, and of course committed to finding true love as evidenced by the requisite proposal.
Heroettes so far have had no careers, no particular talents, no net worth in the asset column, not terribly charming on the whole, and as long as they are cute and sympathetic characters from being someone's dumpee, they are hired

Trista was a cheerleader and hygenist, Mer was a model and wannabe chef, Jen was someone's assistant, Deanna was a bartender and newbie "realtor." Jillian will be the first with a career that seems to be successful.
