Ok, this is how you, or generally people who educate themselves by reading conspiracy theories, view banks and how they rationalize their participation in this scam. That what you described is a classical misconception about banks. Now I am going to explain to you what the facts are.
See? You don't care what other people think. You've told it enough times that you can't imagine a world without debt; without middlemen granting loans, borrowers etc., but this community shows you that this world of free trade and freedom of choice exists. There can be transaction settlement, exchanging, trading without debt. Besides, transaction establishment existed long before debt became a thing.
As far as I've read, there's
completely nothing irrational from NotATether's post, but it's nullified, because it doesn't encroach the way
you understand money.
So, this is a legitimate business of creating debt, investing in debt, and settling debt.
Debt isn't a bad thing, by default. Borrowing money can surely have a positive impact, and there should be. Debt redistributes money into the economy, incentivizes people to become productive, works as an investment whether that's from private companies or from the government itself, helps people acquire a house to live etc., but you're naive
the least if you deny the downsides. It's an instrument that causes asset bubbles, impinges on the low-income groups due to high interest policy, leads to bankruptcy, causes inflation etc.
