He gets right to the heart of the matter in the second paragraph in which he writes,
Profits simply cannot be separated from "people and jobs." Indeed, the highest profits come to those who best provide for the public, usually creating more jobs and satisfying more people. This is economics 101.
I would also add that because the profit and loss calculation is the guiding criteria for entrepreneurs, it is crucial to keep society free if we want to ensure that production is directed to satisfying the most urgent desires of society. Only free market prices are determined by the personal preferences all market participants. In such a free society, was are assured that those entrepreneurs who earn profits do so precisely because they satisfy their customers in the most efficient way.
