In my experience, with comments from others whose opinion I trust thrown in, it really depends upon the company you end up with. There are good and there are unbearably bad outfits.
In addition, it's a strange career, in that one becomes locked into one company fairly early on (I'm talking airlines, here). It's not simply a seniority thing ; other airlines will exclude applicants above a fairly young cut-off age, admittedly with occasional exceptions. I'm talking UK airlines, here.
Combine the above two factors and you can understand why some pilots might be desparate to get out if they're locked into a "career" with a rotten company.
One very noticeable development, certainly in the outfit I work for, is the recent (last few years) dramatic increase in pilots who declare themselves as being absolutely desparate to get out. Some are recent, young recruits ! If that's a continuing trend, then there'll be big problems ahead, mainly a fall in quality, standards and safety, not to mention the attractiveness of the profession.
