When crises arise, economies handle them. More importantly, well managed economies prevent economic crises. Economies become flawless servants to something greater, namely, us and our lives. We know we can depend on them to manage the household for us, so we can get on with our real life's work, whether it happens to make money or not. A sure sign of bad management is when we don't have time to think of anything but household problems.
Every relationship takes on an economic hue.
Meeting basic demands becomes a life consuming activity, until we have no time or energy left for anything else. Moreover, any disturbance can spell disaster. Losing a job or contracting an illness can wipe us out and put us on the streets. One or two major banks or corporations going bankrupt can trigger a collapse of the financial system. Third-world countries defaulting on loans can bring down the world economy.
