Also known as "simple living."
In our modern-day society, people often seek to buy happiness and find that materialism often does not satisfy. Some of these people will choose to leave the “rat race” and live a simpler, less stressful life. A simpler life is less costly, so people can work less and have more time for themselves and family. Voluntary simplicity is not about living with less of what money can buy, but about wanting less.
Moving from a lifestyle of greater consumption towards a lifestyle based on voluntary simplicity is called downshifting.
