Answer:
Economic competition is inefficient and wasteful
Explanation:
The statement best describes an attitude shared by John D. Rockefeller, Andrew Carnegie, and J. P. Morgan is "Economic competition is inefficient and wasteful."
This is evident in the fact that all these three aforementioned wealthy Americans were popularly known for their tendency to develop any form of monopoly in their various business industry.
To them, the existence of economic competition leads to inefficiency. Hence, they always prefer to eliminate the competition, before committing massive investments for the needed growth and development, instead of outwitting the competitors.
