Great article Oliver.  I particularly like the illumination of the fact that due to the ever present, inherent and necessary costing/pricing system never is a true and actual equilibrium of costs and individual incomes attained, but rather the fleeting mirage of such due to  increased borrowing. Thus A + B is never not in effect. And thus both the “interest is the only problem” cranks and the “the interest can (ideally and mathematically) be paid” ethically challenged non-observers of the dominating position of the business model of Finance….miss the mark. 🙂
