Profit-Seeking and Will to Power

As has been previously discussed, an equivalence between Self-Interest and Profit, taken for granted by most Capitalists since Smith, is not easy to reconcile with the traditional equivalence of Self-Interest and Will to Live.  So, though not usually explicitly cited as the reason, that discrepancy might explain the appeal for them of Nietzsche's alternative to Will to Live, Will to Power, i. e. because of the possibility of equating Wealth and Power.  However, the latter interpretation of Nietzsche's principle misses one of its significant nuances.  For, he characterizes it, more precisely, as seeking to "discharge strength".  Accordingly, it is more precisely applicable to the act of spending, as is expressed by the common phrase 'spending power'.  But, that act is itself independent of any increase in wealth that might have preceded it, e. g. money being spent might have come from selling something for the original purchase price.  Furthermore, a discharge of strength that empowers another has high value for Nietzsche, but is forbidden by Capitalist Egoism. So, Will to Power does not ground the equivalence of Self-Interest and Profit, despite the presumption of some that it does.
