Final answer:
In a country with a mixed economic system, policies to achieve low unemployment and reduce inequality and poverty can sustain political support for a market economy, benefiting economic output.
Step-by-step explanation:
In a country with a mixed economic system, the government believes that the economy must also support policies to achieve low unemployment.
By implementing measures to reduce inequality and poverty, the government can create an environment that encourages political support for market forces.
These policies can help build social support for allowing markets to operate, ultimately benefiting the overall economic output.
