When John Calvin legalized money-lending at interest, he made the bank account the standard of values.
When the bank account became the standard of values, people ceased to produce for use and began to produce for profits.
When people began to produce for profits they became wealth-producing maniacs.
When people became wealth-producing maniacs they produced too much wealth.
When people found out that they had produced too much wealth they went on an orgy of wealth-destruction and destroyed ten million lives besides.
