The premise is a bit skewed toward the "love" angle because that is what we've been exposed to lately in everything from "The Bachelor" to that bomb "Mr. Personality."
However, if human nature were to win out, then the choice would definitely be the money. It only makes sense. The money is a "known" factor, the guy is an "unknown."
Why are we supposed to look down on someone who makes the intelligent choice? I know I wouldn't.
