Imagine you can choose between a 4/10 who is sexually attracted to you and a 8/10 who is attracted to you because of your wealth? Suppose you have a very good lawyer so divorce won't present a problem. Which do you pick? If you pick the 4/10, how ugly does she have to be before she ceases to be preferred? And how low does the 8/10 have to go before she's no longer a good deal if you pick that one (7? 6? 5?)?
