GNP and Capitalism

The term 'Gross National Product' is a misnomer--what it signifies is a total of not products, but of the total market value of all products.  So, it is not impossible that one item, produced instantaneously, could occasion a higher GNP than might a vast multitude products and services, requiring much exertion.  Now, among the 'leading indicators' of an Economy, the GNP is the one that is essentially Capitalist.  For, it uniquely measures the wealth of a nation, as Smith characterizes his system.  Likewise, therefore, as far-fetched as it might be, that one scenario illustrates the essential irrelevance of Labor to his system, and, thus, why the exploitation of Labor in it of no interest to its advocates.
