Indiscriminate economics

Indiscriminate economics
Megan McArdle quotes the following:

“Our country has not,” Schroeder said, “become economically strong through the law of the jungle, through indiscriminate hiring and firing.”

Is it really necessary to point out that no country (or business) becomes economically strong “through indiscriminate hiring and firing.” They become economically strong through discriminate hiring and firing.
