Answer:
Several regions of the world had capitalist economic systems before 1990.
Step-by-step explanation:
Most of Western Europe, including countries like the United Kingdom, France, Germany, and the Benelux countries had capitalist market economies. They ranged from social market economies to more laissez-faire models.
Both the United States and Canada had well-established capitalist systems, though Canada's economy had more government intervention.
Japan developed a capitalist economy after World War 2, though it featured more government guidance and corporate collaboration.
Other developed Asian economies like South Korea, Taiwan, Hong Kong and Singapore also had capitalist systems, though often with a strong government role.
Many Latin American countries like Mexico, Chile, Brazil, Argentina, etc. had capitalist market economies, although they were often mixed with elements of state control. Income inequality was also high.'
Countries like Australia and New Zealand had free-market capitalist economies with strong social safety nets and government intervention.
Some Gulf states like the UAE and Saudi Arabia were developing capitalist economies fueled by their oil wealth, though typically with authoritarian political systems.
A few countries in sub-Saharan Africa like South Africa and Kenya had functioning capitalist markets, though they were often combined with significant state involvement in the economy.
So in summary, while the majority of the world's population lived in mixed economies or socialist/command economies before 1990, there were diverse capitalist systems present in many regions, especially Western Europe, North America, parts of Asia and some countries in the Middle East, Africa and Latin America.
