No it is not negativity, it is reality!
I think some of the "negative" posts are just to make people aware - it is a long and hard road, and maybe you should consider a cheaper option then the £100.000 Zero to Bankrupt Hero, as to many people are naive, and without proper foundation for what they start.
Be prepared to keep your ratings, do other work for few years, and maybe dont expect the golden gates to open straight away.
Have a sober plan, still this will not secury you anything, but at least it can help you to avoid complete ruin!
For me it seems to many want to get into a shiny jet straight away, maybe more should lower they initial expections a bit more, and maybe get some more life experience first!
Be prepared to loose the money the training will cost you, and the money to keep yourself current! And maybe the upturn will come in the end, maybe it won't, we never know.
But now all can see, nothing around! Maybe next year!
