If that book is what told you that what the banks did was legal, then I'm going to go ahead and not read it because that's a pretty strong indication that the authors don't really know what they're talking about.
It does NOT say everything banks did was legal. It does track almost 30 years of legislation which, piece by piece, deregulated the mortgage & securities industries so that MUCH of what the banks did [e.g. subprime loans] was legal.
