I don't think my industry has a future past 20 years
I wouldn't change careers into aviation based on that, the industry is not a good way right now, and the outlook is uncertain.
However I assume this is not the main reason you want to change, and more chase a love for flying.
There is a lot to consider, remember getting an fATPL as it's referred to doesn't equal instant job, if even a job ever. There are a lot of freshly qualified pilots who cannot find work and have been looking for years.
That does not mean there are not jobs out there, but they are very rare and with p2f pilots offering to work for free, it reduces your chances further.
I say get a PPL, if you love flying I'm sure you would be happy to just fly as a hobbie and maybe in the future you could do an FI rating and teach people as a hobbie job, and you will of course be able to count that time.
Make sure you really do love flying as much as you think, going from 0 to hero in an integrated course in my opinion is madness, aside from the cost, committing to something before you really know what its all about is mental.
As for training in the states, there's a divide on that. Some say its a rip off, you get quoted low prices but they don't reflect all the costs and don't forget extra hours will most likely be needed, very few are ready on the minimum hours. However some says if you play it right, do your homework and get things sorted before you land there, you can get your training costs down.
Overall, what I'm saying is spread your training, take your time, be realistic and understand what you are up against.
FYI, I'm a newbie too in a very similar position, and have done a lot of homework on this so far. Currently I'm working away in IT while training on the side, eventually I'll get my PPL then I'll probably instruct for a while for fun and to build hours and when I think there may be some oppurtunites in the near future, I'll look at getting my ATPL, CPL and I/R.
