I scanned it.
I think the point that needs to be made though is that it is not a sustainable model. The point needs to be made because some people are too dim to understand otherwise and go off thinking "what a great idea, why don't all companies do this." The bleedin' obvious answer is because it would not work.
It might work in this very specific case, but let's use our imagination and think how this would work in another sector. Let's take say er, English apples. Can you imagine what it would do for sales of our own apples if we paid the pickers £50 an hour? You'd never see a Cox on the shelf ever again. The entire country would be flooded with French Golden Delicious and the whole British apples industry would cease to exist.
How long does the company have to keep going and keep making a profit before you will say they are sustainable? He did this 5 years ago, his business has expanded and he is making more money (for the company) than ever. That seems to say to me that he is doing very well on the sustainability front.
