I think it's a societal travesty that "morals" and "self dignity" prevent (the vast majority of) very attractive girls (think 5'10, skinny, perfectly symmetrical face, etc) from reaping the full compensation they deserve. I knew a few girls back in undergrad who were sugar babies. $1,000 for a few hours was apparently quite easy.
It's not unlike if a very rich man decided (stupidly) to hold cash in Argentine pesos. Losing return-generating potential with every passing day.
It's ironic I say this, because I'm super conservative (according to my peers). Staunch pro-life, against gay marriage, anti-LGBT, etc etc.
But I think using subtle social pressures to deny/shame a person('s right) to their full potential is a shame.
