On a side note:
It is a protection racket that essentially pays for the costs related
to globalization which is absolutely critical in the science of the
stabilization of wages both locally and globally (sometimes referred

accurately addressed to and entitled "Letters to The Corinthian..
Canal Company")

And if you have a tool in the toolbox that works that nobody questions
and very few comprehend then you use it
Or else you have to ask "what happens when you stop paying your
protection money?
