I am not sure if you mean would I pay 50k for MY training, or fund another coz I was basically just rich! BUT
In Scotland at least, we dont pay to go to Medical School, and then the NHS or Private Sector pay for further training as long as you're working with them, so theres no need for 50K for this.
AND
Who on earth wouldn't want to fly for a living (excluding some Ryanair FOs)anyway???Even if it does require initial outlay!
Well thats my young and naive posting, thanks
