It's a shame, and I'm a person that would not endure indignity like this for any amount of money (probably unless it was a ludicrous amount; we really don't know until the money is on the table in front of us), and I'm sure there are lots of proud people like me, but when these people say they'd rather do this than toil in the fields for $2 I have to say, as disgusting as it is, it's their choice.
To say you don't like it is to say you wish there weren't people willing to pay for this, perhaps you find those people disgusting, and that you wish these people could find a less degrading way to make good money, but at least for me, it is not to say that you think they should be prohibited from doing it.
