Doing business like that works for a while until you've gone behind and screwed too many people.
Real life be it in business or in personal relationships ,teaches the exact opposite, which is why skyfairies were invented..because only a minute percentage of people ever get "found out"..and the more intelligent ones noticed that fact a long long time ago..
Modern "control" ( now that the myth of sky fairies no longer work ) is now down to CSI..where Joe and Jane 6 pack are told to believe that you really can "enhance those pixels" and read a number plate or ID a face at 100 metres from the security camera..or reflected in the car driving the other way down the freeway..so they see the "security cameras" and are apprehensive enough to "toe the line"..
You are saying not is that "sustainable", but is it "moral", specifically does it match "your personal moral code"..and if it doesn't it must be wrong ( there I might in some circumstances, agree with you ) ..but to say that all deeds that do not match your personal moral stance will inevitably result in failure, being "found out" or retribution ? ..
The real world does not work like that for most people ..if it did the owners of Lehmans would be now homeless or in jail..the news is ..they are not..
We are each in a fight for survival with each other and with all that is outside of us ..enlightened self interest is one way it can be coped with,but turning the other cheek, telling all, anticipating the best in others gets you broke or shot or homeless or in a recent case even eaten..
The people who head up the largest businesses and institutions, did not get where they are , by being 100% open about what they were doing ..very very very far from it in very very very many cases..they have a name for those who are 100% open.."lunch"..
