It is not a case of being principled, it is the fact that I am astonished that year after year / course after course , people walk into this not with their eyes open , but with them firmly closed.
If you see, for successive years, FO's being dumped on the market with circa 500 hrs on type & virtually no chance to get further employment, why not find another method, or another company to donate your money to ? crass stupidity is not making mistakes, it is failing to learn from the mistakes of others that are staring you in the face.
