There are enough complaints on here about poorly designed, and poorly maintained aircraft, that so many pilots are forced to fly.
Nobody has ever forced a pilot to fly a " poorly designed, and poorly maintained aircraft". Each pilot has taken that decision based on his own interest (ie looking out for #1). Weighing risk and rewards!
It would sound like the posters are suggesting that the private aviation industry cannot be depended upon to provide the quality aircraft you want to fly, without someone you hire, watching over them. Who would that be?
1. If we depended on govt to improve transportation we'd all be walking barefoot still.
2. Nobody ever hired the Govt to "watch over them". The Govt runs a protection racket.: Give me $ to protect you, or I will make bad things happen to you!! Ever noticed that ze Govt always rely on outlawing competitors for their "services".
3. Nobody has a better motivation for ensuring safe flight than the ones with their backsides on the line.
