One of the biggest problems with this country (and many other countries) is that people are borrowing too much money compared to what they can afford.
If you borrow £40-100k for flight training then what are you going to do when you need to buy a car or get on the property ladder or want to go on holiday? You're talking about borrowing more money, if you had a mortgage plus your flight training fees you could be in almost a quarter of a million in debt!
I'm pretty sure thats a position you wouldn't want to be in and a position that your future wife wouldn't want to be in either.
