The economy is a major force driving our lives, from the purchasing decisions we make to the public and private institutions we support. It determines how wealthy nations and their people are, and consequently becomes a determining factor for assessing quality of life. On the other hand, when the economy collapses, it brings us enormous devastation and takes wealth and prosperity back from the people. When an economy ceases to grow, it’s not easy –or maybe even impossible — to bring it back to the state where it used to be. Suppose that we are lucky enough to see economic growth and prosperity again, how can we know that a collapse is not going to happen in the future? Maybe it’s time for us not to rely too heavily on conventional economic theories, but instead start to look for a more sustainable and effective economic strategy. The Sufficiency Economy might be a better solution for mankind to pursue and improve upon.
