They should not go. Get their PPL and do things slow, very slow.
It is easy to see that there are no jobs out there(for reasonable T/Cs) so why are they in such a rush?
Stay cool and get to know a few people before you do anything.
Why do you spend 100 000 euros on a career that there are no (reasonable)jobs in?
I am generally not disturbed if someone has worked a lot and saved up some money and do it in a slow modular manner so they know a little bit about it before they are at the finish line. But when people pay with money that they don't have and end up in high debts... That makes me sad.
