"The goal of a command economic system is to make members of society more equal" is the correct answer.
The command economic system is based on the Marxist perspective that states that society is made up of different social classes that struggle to prevail. The capitalist class exploits the working classes and keeps the surplus value, which is the difference between the value of the goods produced and the costs of producing it.
Understands that both costs and prices are static, unlike the market economy that is based on allowing supply and demand to interact to establish prices and based on these then all costs are dynamically established.
This is why the State must intervene and control the economy to prevent the capitalists from continuing to enrich themselves at the expense of the workers in order to achieve a more equal society.
