ABSTRACT
This paper is based on the two central theoretical options of Samuelson regarding the scientific heritage of his former Harvardian teacher, Schumpeter. Specifically, this paper details the intrinsic limits of the macroeconomic approach to the dynamic nature of capitalistic economy and its periodical instability. An alternative approach is proposed, based on a disaggregate model and the theory of opportunity/value, which leads to a "Dynamic Discriminating Equation" able to distinguish between physiological and pathological interruptions of the capital accumulation process. This is the difference which macroeconomics, with its fatal "blindness" with respect to dynamic process, is unable to distinguish. A "blindness" that Schumpeter in his time had correctly diagnosed but never rigorously explained.
