The only facts are the ones we can actually measure.
I've run a search on the aviationjobsearch site with the keyword "pilot". The results are: 355 listed jobs, for the whole world. That looks a bit risky to invest and hopping to get a return of the invested amount in that training. 1.5 years on training plus 3 years on a lower initial salary means that only after 5 years if things run smoothly we get the return (break even) of the investment. This looks less appealing if we compare to spending those 5 years on a 9 to 5 job paying half of the pilot net salary.
Also if the world economy and stability means people will be travelling more it will also mean higher fuel prices.
Let's also not forget the regional differences. The lack of pilots in Asia is different from EU and from USA.
I'd like to have more certainty before spending up to 100k in training as a full time occupation.
