Sullivan itemizes a few dozen ways in which we are being fleeced by corporate capitalism; the hidden fees, the surcharges, the rule changes that lead to big jumps in interest rates, the installation charges that were conveniently not mentioned until after the fact. And he provides a 'toolkit' of approaches for eliminating or reversing those charges. All very useful, I'm sure.
Maybe more useful would be if Congress would re-assume its responsibilities, which it relinquished under the Reagan administration, and re-pass the usury and consumer protection laws that were either gutted or that didn't keep up with the 'structural changes' that have occurred in American capitalism during and since Reagan.
