This video offers a good overview of Max Weber’s thesis in The Protestant Ethic and The Spirit of Capitalism. If you haven’t read it, you might be surprised at how theological the capitalist work ethic is according to Weber. You might also be surprised at how he sees Calvinistic theology motivating the desire to work.
While the video is a good overview of Weber, he was wrong, both on Calvin and on the connection between capitalism and Calvinism. A better resource for the connection between the isms is Calvin and Commerce: The Transforming Power of Calvinism in Market Economics. Calvinism correctly understood and applied is good for the economy, but you’ll have to read the book for yourself to see the whole picture.
