Über den Stellenwert der Ökonomie braucht man sich eigentlich nicht zu streiten:

When people refer to the firm, or any other institution, as „viable“, they are often referring to economic viability. From this preoccupation with the economic dimension stems the assumption that most of our problems are economic too.

Solvency, it is true, is a prerequisite of business activity –  to trade while insolvent is illegal. Profitability, too, is a prerequisite – lack of business confidence is not illegal, but it is lethal. So these affairs are of primary concern.

But they do not (as many suppose) constitute the goals of the enterprises. Rather are they the constraints under which it operates.
