The issue with the current system is it gives a lot of money and power to banks, and finance.

The issue with the proposed system, is that debt is actually a good thing for normal people. For example if you are young, productive, and come from a poor background, then you might buy a house with a mortgage. If debt is more expensive, then you are less likely -- and older people (and rich kids) are more likely -- to be able to afford these houses.

You might say that the current system is unfair, because wealthy people won't need loans and can put their money to work exploiting poor people. But in a system where we redistribute wealth this way, the impact is harshest on the poorest people. The things that are limited in supply and high in demand will immediately go up in price. The things they wish they could buy, and plan long-term, will become unattainable. And I've not even gotten onto how this would affect productivity.

Everyone is focused on how the rich are getting richer. This is inevitable in liberal societies. The goal should instead be to stop the poor getting poorer, and I'm going to need some serious convincing that handing people a CBI, instead of providing debt, is going to actually benefit and not hurt them and the whole economy.
