What are differences between the roles that individuals and government play in the economy

In a mixed market economy that we adopt in united states, the roles for each of them are:

Individuals : Producers & consumers

Government: Regulators

Explanation:

Mixed market economy give most of the control over the economy to the private individuals. As the producer the individuals will decide what to produce, who to produce and how should it be produced. As the consumers, the individuals will decide the type of goods that popular in the market and how much saving they will use to purchase it.

In this system, the government will try to play the role as the regulator. They will create laws/rules to ensure that the competition among producers is fair and the consumers safety will be guaranteed from the products.
