As far as I can see there's no shortage of experienced F/Os with proven experience and the right type ratings; however, the critical change in the last 7 years is that no-one wants them. The future is all about cheap trainees who have paid for their training and will work on highly reduced terms and conditions. There's no shortage of those either.
The result of all of that is there is virtually no career left; it's curtains if you are an F/O and are out of work for more than 12 months. I've half a mind to cancel my Flight subscription after I read that recent gibberish.
