Honestly, I don't think I follow what do you mean by "[...] they would not find someone to work for them."
Reliance on oneself is a good, and admirable - I quite understand this sense of the "entrepreneurial-ship" you refer to. And those who are able to, have no need for God; they can sustain themselves each on his own personal religion.
But I call your attention to the fact that people are very fragile and quite lucky to bear their burdens well. Such self-reliant "entrepreneurs" are singular individuals. Most do not bear their burdens well b/c life is dure. It is these who need God.
