The suggestion of not having anything to do with these mazes is in effect a suggestion not to have anything to do with any extremely successful company as far as I can figure out - so, at what monetary point will a company become a maze?
It's not at a monetary point. It's usually when the company has succeeded to the point that it's not in danger of failing, even if inefficiency sets in. Once it reaches that point, then it's a matter of how long it takes the culture to rot. (Most cultures rot eventually.)
I wonder if "immoral maze" explains our politics as well, and if it has the same cause. The US hasn't been in danger of failing, even if the government became insanely inefficient.
