Big trouble for Wal-Mart would in turn mean great news for consumers. The FTC is doing everything it can to see to it that that never happens. So-called antitrust regulation has for 125 years been a tool of the crony capitalists. Its effect has always been to protect (politically-connected) competitors from competition, all in the name of "the public interest"!
