This actually is not true. Some time ago I had opportune to speak with a homeless man about his situation, and his options. It turns out that he is offered money for sex quite often, perhaps daily. By his telling, he has never done it either.
The proposals are from gay men.
There may be the occasional statistical outlier. But, on average, you are going to see homeless women offered money for sex a great deal more often than homeless men.
If you want to rebut that, please cite sources, not anecdata. I've had a class on homelessness and public policy. I spent nearly six years homeless. I still blog about the topic. Your sample of one doesn't remotely convince me that my assertion is inaccurate.
I didn't say it never happens. I said it is much less common.
Your casual dismissal of my knowledge as mere anecdata on par with theirs isn't in the least bit "interesting".
Homeless men with no skills sometimes find day labor jobs. They are much less often offered money or a place to stay in exchange for sex.
I used Glass Ceiling as shorthand for removing barriers generally. Given the response here, I don't think it's worth the time and effort to try to "clarify." I don't think most people here actually want to understand the point. They are too busy shooting the idea down to wonder if there's any merit to the idea.
