Are there countercyclical cultural trends?
In other words, which trends or tendencies flourish when the economy is underperforming? This source makes a (weak) case for facial hair. In 1926 George Taylor claimed that hemlines went up with strong economies; presumably skirts become longer when times are bad. This post and chart suggest that dystopian science fiction movies go away in bad times.
Which of these tendencies — if any — are the most reasonable to actually believe?
