No. Not at all. Without interest nobody will lend money for new businesses and innovation. Interest is important. It just means that you value having something right now more than having it at some point in the future. If at all.

However I agree with you that all power lies in a few hands. Those are the people who are not locked in a cage if they lend money with interest or counterfeit money. Money in that case being the enforced legal tender. It is that inequality between those people's rights and ours that is the problem.
