Fred.
You say yourself that you pay it back via a reduced salary, so you don't have to fork out / obtain £60000+ now.
How can you moan about it then.
What are the alternatives?
Most people fork out the £50K with no guarantee and then spend months, stressed, desperately searching for something, anything at all, facing bankruptcy.
Which position would you rather be in, having all these uncertain factors and the debt, or to receive a walk in job, flying modern a/c and still earning a respectable wage?
I'm not taking anything away from your merits or achievements, but just think all new pilots are in the same boat. Some have it relatively easy some alot tougher. There will always be someone better off than you, but indeed worse off also.
