We need always to offer help to people and countries, never harm. We need to resolve conflicts to mutual benefit. Let's make the 21st Century the Century of Cooperation. Equality, not inequality. Countries where income is distributed more equally are wealthier than countries where income is distributed more unequally.
Equality increases supply and demand.
When everyone is equally employed, skills improve and product quality increases. Equality increases demand because full employment increases effective purchasing power. Inequality reduces supply and demand. It reduces supply because underpaid people produce less and goods of lower quality than well paid people. Unemployed people produce nothing.
