Why do we need a set of laws outlining the way business can operate? Who's business is it how a business operates? Provided there are agreed remedies should those business cause harm then let them do what the hell they want. What's the baker going to do? Poison his customers? Why? Do you really imagine the banks would have played casino had there been no state at the ready to bail them out? Of course not. The very presence of the state is what fired the recklessness. I didn't say the criminality of the bankers was sponsored by the state (the other way around maybe), what I'm saying is the state intervening to offer incentives and punishments will always favour those who can best manipulate the rules. The rich don't pay tax, the poor do. Why? Because the rich can afford accountants and lawyers and those accountants and lawyers are a damn sight smarter than the unambitious drones who lack enough dignity to work for HMRC.
