In the aftermath of super storm Sandy, there have been plenty of cases of women trading sex for gas. (Craigslist has facilitated this and documents that this is actually happening.)
Most people think that this is a situation unique to the aftermath of a major natural disaster. I disagree because I think we will see more of this in the future. It’s not because of natural disasters or civilization collapsing. It’s because female employment will collapse. Many women are directly employed by government, employed by quasi-governmental entities like universities, or employed because of government policies (i.e. affirmative action). These women aren’t doing any real work. With the fiscal cliff potentially arriving or just the money running out for government in general, these women’s jobs are in jeopardy. The government (and private businesses) will be not be able to afford to keep women who contribute nothing to productivity.
What is going to happen to these women? They will lose their jobs and not be able to find another one because jobs like HVAC, climbing to the top of 1700 foot tall transmission towers to repair them, and rebuilding after natural disasters require someone to do real work which means only men will do them. Government welfare won’t be much of an option since the same financial problems that killed their jobs will also prevent sufficient welfare spending for them. That leaves prostitution as these women’s only option, a lot of it will probably involve barter (i.e. trading sex for gas).
