President Ronald Reagan rejected the theory of Keynesian economics, this theory proposed by John Maynard Keynes, embodied in his work General Theory of Employment, Interest and Money, published in 1936 in response to the Great Depression of 1929, the central principle of this school of thought is that state intervention can stabilize the economy, Keynesianism is one of the best-known economic theories, its main characteristic is that it supports interventionism as the best way out of a crisis and as a mechanism to stimulate demand and regulate the economy in times of depression.
<span>I think the fact that there was no single ruler in the stateless societies allowed them to endure for many centuries. No family had too much power than the others. The way they resolved their problems also helped them survive for a long time since it allowed them to peacefully talk about the issue without violence. They also had a very organized way to decide to who to pass down the possessions and property too. People were also separated into age-sets where they would pass stages of life with other people in the same generation.</span>
