Churches tended to thrive more in countries (like USA) where church and state were separate
By the end of the 1800's church attendance had declined (more so in the working class than the middle class)because:
1. too many people but not enough churches
2. people (lower class especially) began to see the church as "the man" and "the man" was on the side of the middle/upper classes
3. church "feminization"
