The problem with permaculture

 I've never really seen someone elaborate like this, via a major outlet, about the problems with how permaculture is currently taught. The author has a number of valid points. His major complaints center around money and philosophy:

-Because of the base cost, permaculture design courses are usually out of the question but for a select few.
-Throw in the cost of books and even more people are unable to gain a certificate.
-Some in the industry recommend using expensive equipment and machinery, instead of low cost methods, further driving up the price of a typical project.
-Permaculture teachers view sharing their knowledge as money making tools/income generators, which runs counter to the similar, yet still very much different, agroecology movement. 
-Courses "sometimes seem like a publicity campaign for companies that market organic products". In one particular course he mentioned hundreds of plugs for popular products.

What do you think?

-A billion dollar project in Florida spent over $700,000 moving mature trees to their latest project!

-Will this ambitious wine loving, Brooklyn based duo be able to pull off the world's first rooftop vineyard? It's been a few years in the making and they are now oh so close.
