Is the business organization or labor force more important
for the strength of the economy?

The labor force is more important for the economy.

Explanation:

Though business organizations form an integral part of the economy, their existence is not mandatory as long as every individual labor bears the ability to work on his own. This is because the individuals working separately can also run the economy efficiently without the need of a business organization. A business organization merely pools the labor under one roof and combines together the services that the labors can offer in order to fetch larger benefits.
