Anyone who lives within their means suffers from a lack of imagination.
Oscar WildeKey questions

• What is the future of money and banking?
Summary
The banking and personal finance industry can do a useful job in smoothing out consumption patterns over people’s lifetimes: lending to them when they are young and cash-poor, but with most of their working life ahead of them; helping them save for family, house buying and retirement when they are older and earning at their peak; insuring against risks and misfortunes along the way; and, finally, paying out through pensions and annuities when they quit work to spend more time in the garden. Businesses also need credit to grow, and in order to employ people to generate income and savings. Balancing out the demands of these groups and their various needs, across the whole country is a big and complex business, begetting an enormous financial services industry. The flow of credit has to be managed and regulated through complex regulation alongside other tools, such as interest rates. Stabilizing these financial activities is a headache for the authorities, and sometimes – as in the financial crisis of 2007– 2010 – things go horribly wrong.

Introduction
This chapter deals with something close to many people’s hearts: money (and saving). Money is central to economics because spending it greases the wheels of commerce and consumption. Saving our income instead of spending it can finance investment in the practices and technologies that fuel wealth creation. Both activities also entail the creation of financial institutions, such as banks, that help us manage this.
