Even though military flying schools tend to feel like sausage machines at times they will not pass someone that is not up to standard. Civvy flying schools however always have the commercial pressure to pass students so they can get paid. Big difference.
Another thing, military pilots learn most from the daily interaction with other pilots at the SQN and in the crew room where open discussion about events and most importantly f^&% ups is encouraged without the risk of persecution. It is difficult to see the same culture in a commercial company.
