The system of interest (usury) is controversial in the modern financial system. Interest is used as a means for banks to profit at the expense of borrowers, leading to a significant accumulation of debt due to accrued interest. This imposes a heavy financial burden on individuals and families, hindering their ability to invest and achieve personal economic growth. Moreover, the interest system can exacerbate poverty and economic inequality, making it difficult for disadvantaged individuals to access financing due to high interest costs. Therefore, embracing such a system is not just madness; it's akin to suicide or granting banks a form of debtor slavery. Personally, I have experienced the challenges of this issue, especially with repeated interest rate hikes.
