Your beliefs about usury fail both internal consistency inside Bible and consistency with reality."Owe no man anything, save to love one another: for he that loveth his neighbor hath fulfilled the law." Rom 13:8
There are lots more like this. The rules around debt in scripture limit it heavily, essentially for the aid of the poor, and make it uneconomic as a commercial enterprise. I'll take the Bible any day over the economic theories of modern man.
Last I checked fully 30% of all corporate profits was in the financial sector. So yes they are. Literally even: in farming, interests costs on land are more than what the land will profit a farmer in capital returns.
This one it has....
"Do not charge your brother interest on money, food, or any other type of loan." Deuteronomy 23:19
Bankers are evil doers and should repent.
Full proper words would be lending money at interest rate greater than zero. To shorted this I will use lending money.
Let's deal with Bible first.
If lending money at interest rate greater than zero is sin, what is punishment for this sin? And what is it's sin offering?
And if lending money at interest rate greater than zero is sin, then why it is allowed to lend to foreigners? So Hebrews aren't allowed to do evil toward other Hebrews, but are allowed to do evil toward foreigners? Why is so? What logic makes this command moral?
Why Jesus in Parable of Talents uses money lending as example how we should behave? If money lending at interest rate greater than zero is sin, then why it is this example? How can evil be example of good?
Why Jubilee for debt exists? If money lending is evil, then why this regulation exists? To make analogy with monogamy-only people. Monogamy is cool, polygyny is evil, then why laws regulating polygyny exist?
Now let's deal with reality.
Wage is payment for labor, profit for providing service/product and interest rate is payment for providing money. If lending money at interest rate greater than zero if forbidden, do you know what you have done? This is price control, with price of money at zero. Same price as air.
Only thing in practically infinite supply have price of zero. Does money exist in infinitive supply. Can it be made to exist in infinitive supply? O, yes. I didn't know you consider hyper-hyper-hyper-hyper-hyper inflation blessing.
Money is also asset which has opportunity cost. There are alternative usage of money. According to you, only moral usage of money is to buy stuff for me and invest in my business. If I have money and another family need home, only moral course of action is for me to buy house and rent family house. Is it evil to borrow money to family, so that they can buy house for themselves.
By the way, house is asset, as factory, as tractor. It it morally OK to buy asset only with cash, but buying asset with borrowed money is absolute evil.
In above example who is harm when buying with borrowed money? How money stops being good when used for lending.
Also, why do interest rate exists? Which natural phenomena creates them? Uncertainly and preference for now. For example, I have 10 bucks and want to buy ice-cream. You show and ask me for my money. What are my options now? First is to get ice-cream now. Second is to borrow you money and wait new year to buy ice-cream. Obviously, better choice is to buy ice-cream now.
In other to make it worthwhile ice-cream waiting, it not enough to offer me just return my money back. No, you have to offer extra money for me to delay buying ice-cream.
Banker can consume his million now. Or he can lending his million at 5% which implies than he could consume 1.05 million next year. If banker lends, then he is waiting to improve his living conditions till next year.
So, interest rate is cost of making waiting worthwhile. As such, is it part of human behaviour. Larger waiting period implies larger interest because people have to wait longer before they can improve their life. If interest rate is zero this implies than people are willing to wait forever till their money comes back because they are immortal with infinitive lifespan. Idiocy.
Another approach, also correct, is to notice that same thing is future is less worth than same thing now in our hand. Difference in this prices is interest rate. At interest rate of zero, it would imply that for person would care does he now possess thing or not. Again, total nonsense. Think, you buy car with delivery next week. Car which can get trashed during delivery and I can't drive has same usefulness as car in my garage which I can drive.
You aren't thinking what your Bible interpretation implies. And you also don't know economics.

This is great example of what I call Bible qouting. Biblical interpretation breaks economic law (all economic laws are laws of human behaviours) and results in total nonsense. Off course, author doesn't notice this and is convicted his is correct.
