That quote is taken from The Choice, and is Goldratt's attempt to summarize his philosophy: that his logical Thinking Tools can be used by anyone, and can provide win-win benefits for everyone in any situation. Worth a quick read, I'd say...
I agree that The Goal isn't the greatest literary novel in history; but then it doesn't set out to be that.
For me, the genius of ToC is that it provides a focussed, step-by-step way to get to the big productivity improvements; whereas lean/kaizen, while also very effective, can take an age to get to the same place.
