To me the issue is not about specifically paying usury or even enabling those who sin by taking it from me. I don't expect otherwise from the world - though I do admit I struggle with loving these people who right and left beat me down and steal the money right out of my pocket - money I literally earned by my own sweat. And unlike them I labour assiduously to be honest and fair in my dealings - to my own hurt if need be. I would rather have a clear conscience then shrug my shoulders and be like them.
My real issue is with those Christians who have jumped the fence and stand on the Babylonian side - exploiting not just society at large but fellow Christians. I expect the lost to engage in dog-eat-dog ethics - Darwin's survival of the fittest. This is as old as Cain and Lamech. But I do have a problem with the Christians who have entrenched themselves in the system and are right at home in these various industries and sectors of society - making money hand over fist on the basis of what is essentially legal extortion and Babylonian alchemy. I have a problem with Christians who have baptised this law of the jungle, this atheistic ethic that is completely opposed to New Testament religion.
