If people spend most of their money on Rent or paying Debts, then they won't have much money for food, for pubs, clothes, to go to concerts etc.....

Even if you believe in Capitalism, surely you must admit that the current system is not working.

@DGI nobody believes in capitalism. it can only be faked. when anyone who claims otherwise look at the examples they use and how those align with their short term financial interests: you will find they always do. always.

interest in capitalism can only ever be faked because it is not an ideology. it is just an abuse system built on the disgraceful feeling of greed.

@DGI I admit that the current system isn't working, but you also have to admit that common people weren't exactly enjoying their lives before it.
Concerts, new clothes, vacations were luxuries rarely or never experienced.

@DGI The part of markets is working quite well, but the fixation on shareholder value is breaking it. Marktets and money could work in other ways too.
Currently nothing rely stops rich from getting richer and this is cause by a fundamental flaw in the system.

The demurrage on money from Silvio Gesell could help here.

From the popular British economist John Maynard Keynes:
"I believe that the future will learn more from the spirit of Gesell than from that of Marx."

@DGI Mainstream economic theories are broken too.

Even the IMF says:
"the zero lower bound is not a law of nature; it is a policy choice."

Enabling Deep Negative Rates to Fight Recessions: A Guide

The experience of the Great Recession and its aftermath revealed that a lower bound on interest rates can be a serious obstacle for fighting recessions. However, the zero lower bound is not a law of nature; it is a policy choice. The central message of this paper is that with readily available tools a central bank can enable deep negative rates whenever needed—thus maintaining the power of monetary policy in the future to end recessions within a short time. This paper demonstrates that a subset of these tools can have a big effect in enabling deep negative rates with administratively small actions on the part of the central bank. To that end, we (i) survey approaches to enable deep negative rates discussed in the literature and present new approaches; (ii) establish how a subset of these approaches allows enabling negative rates while remaining at a minimum distance from the current paper currency policy and minimizing the political costs; (iii) discuss why standard transmission mechanisms from interest rates to aggregate demand are likely to remain unchanged in deep negative rate territory; and (iv) present communication tools that central banks can use both now and in the event to facilitate broader political acceptance of negative interest rate policy at the onset of the next serious recession.
