My primary point is that capitalism and Protestantism reinforced each other until both became dominant within modern empire (UK --> US).

And i just think we should re-examine that claim by Max Weber from a materialist/marxist perspective. As Marx pointed out, the relative early development of capitalism in Northern Europe came in part out of the different property relations that existed within these countries, the loss of the commons in the UK is one such example. This was not caused by an abandonment of Catholic doctrine.

Likewise explicit feudal obligations were retained in Scandinavia for almost a century longer than they were in France, supported by the Protestant national churches. Explicit codified serfdom was reintroduced in Denmark under a protestant regime, having been abolished under a catholic (Or at least pre-reformation) one.
