I have a sense that I'm one of these people. I'm risk-averse, perhaps anxious by nature, and I like the structure that corporate entities provide, despite being well aware of how challenging it can be to exist and thrive within that structure at times; and, despite what PG writes in "You weren't meant to have a boss":

It's appropriate, given his audience, that most of what PG writes is very encouraging of the idea that people should just get out there and get things going by themselves.
But, not being familiar with all of his essays, I wonder if someone could point to any that are a little bit more ambivalent about the whole endeavor.
