One of the biggest changes that has changed the outlook is:
years ago you could enter the profession with not too much cost for CPL, gain a type rating for no or little cost, earn a relatively good starting salary for an apprentice, be treated like a professional with reasonable respect, and be able to plot a career if you were competent.
now you need a 2nd mortgage to enter the profession, gain a type rating if you can afford to pay for it, start on an OK-ish salary for an apprentice but with huge debt, be treated like a school kid and trained monkey, have little idea where you all be living in 5 years, and have little chance of surviving till 65 at 100% of todays short-haul roster.
