This sounds like all that debt-free right wing crap that assumes that capitalism would be ok if it weren't for all those bankers. Profit is ok - just not interest. It's deeply silly.
[WS:] It smacks of veiled 19th century anti-Semitism of the "scratch a banker, find a Jew" variety without being overtly anti-Semitic. Without that leap, the whole argument is rather boring and unimpressive. Clever, rather than silly.
