If your enterprise can't at least match the global growth rate, perhaps the world would be better off without you doing it, leaving that capital available to those who can.
And if their are idle resource and people then your argument falls apart because idle resource simply decay (both human and machine) and produce ZERO returns, any positive return is better then that. The history of interest rates clearly shows that interest dose not ONLY reflect an average of growth rates or even the average return on investment activity (which is what you meant to say).
