I understand your point but...
Market forces still rule.
If someone really cares, don't waste time moaning to fellow sufferers here. Go drop a note to SAA with name, date and registration to ask why Captain X doesn't need to stick to the rules. Or find some gentleman of the press who needs to do a story about greedhead airline captains grabbing trips from deserving neophytes while flaunting the rules.
Just remember if you do that though, "What goes around, comes around!" If you end up on the wrong side of the "old boys' network" then you might as well forget getting very far ahead so that my advice is not to do these things. You might end up like ALPA's Timmy "Milkman" Martins, famous for all the wrong reasons, if you inspire a write-up about "Moaning Newbies Face Grim Future Selling Burgers!" instead of "Captain X Is A Greedy Swine!"
What this comes across as is "special pleading," sort of saying that even though it is a rough row to hoe getting a foothold in aviation, you should be treated with consideration by some four-striper. Well, why? Do you also expect to go to the head of the check-out line at the market because you are in a hurry? The best thing is to stop moaning and sort out a solution to the problem, either simple denunciation (when no one likes a rat) or else just sucking it up and laughing it off.
It is funny you should mention that but I am just in the middle of doing an on-line CFI renewal for my FAA CFI (Airplane, Instrument, Multi-engine, Gold Seal, Ground Instructor Instrument Advanced). Oh, and I also have a JAR FI that I haven't even used yet!
So I am sat on the fence; I would have no compunctions about grabbing a trip off some starving youngster if that were done fair and square yet I do try to put something back, yes.
