So every CBA must have concessions or else they will be iced for all eternity?

If what you meant to say was compromise then you might have a point. We can compromise from 100% scope at all levels to a point that reduces large RJ's as contracts expire while not allowing one more seat or weight increase at DCI. We can compromise from 6 weeks of touch drop vacation all the way down to 5 weeks of 5 hours a day. We can compromise from every city we serve being a hub to protect against future AS code share abuse to just adding SEA and LAX to the current list of hubs. We can compromise from C2K pay plus full inflation and restoration of 60% FAE retirement to significant raises while retaining profit sharing and upping our defined contribution. We can compromise from 100% JV balance in our favor all the way down to half. A 50% compromise. Half, or course, now being defined as 51.5% for the rest of the decade is 100% fair and balanced too, since they had the "half" scales in their favor for many years. 24 hour long call can be compromised down to 14.

But saying there has to be sections that lose in order to gain to justify concessions during the most positive and profitable period argueably in industry history, and all for 9/6/4/4 with givebacks all around, well, lol. Yeah.
