I am sorry, but I disagree.
If the business owner and the business were an island onto themselves, you would of course be correct. Yet as long as the person benefits from a multicultural society, one where his female offspring will have the option of choosing careers that are not limited to prostitution or marriage only, where he does not need to live in fear of having a cross burned in his front yard (if he is black) or having an oven door painted on his garage (if he is Jewish), where he does not have to pay exorbitant taxes to benefit those of races he (and others like him) routinely fire or do not hire, and where he is able to peddle his wares to a large audience able to buy, there are certain ground rules set in force by which he will need to abide. The United States Constitution sets them.
If he does not like these rules, he may relocate his business to an area outside the territory governed by these rules. THAT is true capitalism.
