Really?? You've been flying for decades and this is one of the most challenging environments? You need to get out more.
I've been doing this long-haul caper for less than 2 years (and not for much longer, thankfully). It is, without doubt, the least challenging (and best rewarded) job I have done in 22 years of flying. Flying a highly automated aircraft to about 6 radar-vectored ILS's a month is not tricky. My previous job - flying 4 sectors a day in crappy weather to 100 destinations served by precision, non-precision and circling approaches was challenging.
The problem with pilots who have been wide-body for too long is that they really start to believe all the cabin crew and ground staff who treat them like sky gods. By all means take the cash and enjoy the lifestyle, but let's not pretend the job is difficult. Tiring, tedious, unhealthy - yes. Difficult - no.
Most guys I fly with now would soil themselves if they had to do a circling approach.
