From the article:
In 1969, the high court ruled: “Whatever may constitute income, therefore, must have the essential feature of gain to the recipient. This was true when the 16th amendment became effective. … If there is no gain, there is no income. … [Income] is not synonymous with receipts.” Read more at http://www.wnd.com/2013/06/businessman-irs-fears-prosecuting-me/#XxAzCPB1lOzwOFfB.99
In short, whether we wish to support this man or copy his behavior, we must admit he has a point.
If we taxed Sears on every dime they took in, then we would not be distinguishing between profit (income) and expense (receipts).
A household, no less than Sears corporation, is an enterprise that has significant expense. Technically, the "profit" is the amount left over that you have to put in your bank account as savings. Some households are poorly run, and that's why there are a tremendous number of bankruptcies. Some are well run, and wealth accumulates.
But, to pretend that housing, food, clothing, transportation, education, etc., are not EXPENSE is silly.
Well said. To carry it further, your labor is an expense to you personally, both physically and as a decrement to your other pursuits (e.g., spending time with your love ones). I think that is the larger picture of what he is contending.
