I think your friend has mislead you, that £90k figure sounds more like his debt remaining with CTC after one year of working for EasyJet, not his annual salary as a new first officer. I think you'll find the annual salary will be far closer to a third of that (I couldn't say exactly how much new FOs are being offered).
I certainly wouldn't be doing it for the money though, there's a lot of hard work involved, with the exams etc. and the money you need to put in is at its lowest around £50-60k and thats before a type rating. For somewhere like CTC you can expect to pay them around £100k, again before paying for a type rating. So regardless of salary, unless you can afford that without a loan, then you're going to be paying off the debt for a fair while.
As for job prospects, they're certainly below average at the moment, how it will look in the future, who knows? Though I'm sure there are plenty of opinions out there.
I'd suggest starting with a few hours towards your PPL, and seeing if you enjoy flying first, from there its a decision of how you want to proceed, modular or integrated. I won't go into that though as theres plenty of material on it on these forums, a quick search should pull that up.
Good Luck if you decide to go ahead with it.
