No business has morals or we would not have terms like "Risk Management Assesment" as in where the automobile manufacturer concludes that while a percentage of his vehicles will explode frying the unfortunate. It is within acceptable financial boundaries and simply easier to pay-off the impending lawsuits as they happen, than make changes to the manufacturing process.
Its also why all the shonky factories and chemical timebombs are dumped in some black-fellas country.
So what makes you think flying schools should be any different?
