I wonder if there is much correlation between a community's sex life and that community's welfare. But I know that most very conservative countries have struggling (though many are growing quickly) or undiversified economies. Though there are countries that are both very sexually conservative and successful and vice versa and converse.
It could also be that having a sex life is counterproductive when you are trying to get an economy going but once you reach a certain level of development, you need to have either a very inclusive society, a society that props itself up forcefully, or in the case of the Romans, both.
