That's why we also should use a bartering system to keep things in check, just like how societies survived for thousands of years. I'm not claiming to understand the whole machine, however, we know for certain there are rotten practices that make the machine unstable and also much more difficult to understand. Interest and usury are at the core, along with other things that are prohibited by Islam (e.g. selling things that you don't own and several more). Once those are removed, the system will become much more stable, fair, and better off for everyone.
