Changing terminology: "global economy" --> "money makers"


#1

From some Forbes article:

U.S. companies with $10 million to $1 billion in revenue together make up the fourth-largest global economy …

Could it be correct to change it to:

U.S. companies with $10 million to $1 billion in revenue together are the fourth-largest money makers …

Incorrect. What is wrong with the first statement? Its about global economy not about money-making.
