It's not the owners who are doing it.
Your 'gripe' is against the pilots who fly the aircraft.
First step on the road to change is to accept the fault. Only the pilot can commence or continue a flight which breaks the law / regulations / rules of good airmanship. The 'unscrupulous or excessively demanding owners' are sitting in the back, not holding the controls. Collectively, as an industry and 'professional pilots' take ownership of the problem (if one exists) and stop evading responsibility with phrases like 'unscrupulous or excessively demanding owners'.
