Agreed, though I was referring to the type who are doing it purely for the cash.
Good point with the children though, I didn't consider that. The way I've seen these relationships work is that they typically don't last long (I.e. the man gets fleeced, the woman takes as much as she can carry), and the they split, with the man going on to find another or learning from his experience and peering beyond the Barbie-visage in future mates, and the woman repeating the process with another man until her age catches up with her and she settles.
