The Declining Hotness of Flight Attendants
-- You could probably still get a large group of young, hot women to take a job that involves free flights all around the world. But those jobs are no longer open, because airlines stopped firing all the old, fat parents. Thanks to a combination of feminist shaming, union demands, and anti-discrimination laws. Moreover, once they no longer fired people over a certain age, union seniority rules immediately started selecting for older workers, in two ways: layoffs are usually last hired first fired, and older people have a lot of sunk costs in terms of pension accrual and seniority, so they're less likely to leave. If you fly a major airline, you'll notice very few stewardesses in their twenties.
