Final answer:
The fundamental difference between the command system and laissez-faire capitalism is the role of government in economic decision-making. In a command system, the government decides the division of output through central planning, whereas in laissez-faire capitalism, individuals operating freely through markets determine the division of output.
Step-by-step explanation:
A fundamental difference between the command system and laissez-faire capitalism is that, in command systems, the division of output is decided by central planning rather than by individuals operating freely through markets. In a command economy, the government decides what goods and services will be produced, how they will be produced, and who will receive them. This is in contrast to laissez-faire capitalism, where there is no government interference in the economy and individuals make economic decisions based on their own self-interest.
