Isn't this the work by Max Weber? The main idea here is that predestination of Calvin believed that certain people were predestined for salvation, and others were not. But the implication is that material wealth is an indication of whether one is to be saved or not. Weber points out that even though there were always wealthy classes all over the world - he is quite eclectic and treats ancient India, Babylon, China and Japan - modern capitalism and earning money for the sake of earning money, not for enjoying resulting luxuries, is Protestant in nature. I am not an expert on Catholic viewpoint, but many religions (other than Calvinism as Weber sees it) tend to see wealth as a hindrance to salvation - e.g. camel through the eye of the needle etc. But the doctrine of karma etc. do tend to emphasize work for work's sake. So I am not sure I completely agree with Weber (he has works on Hinduism, Judaism etc. which are also insightful and unique takes on religion).
