I think another good way to put this in perspective - consider the commuter carriers. With a few rare exceptions, they've retired just about everything from the 1970-ish era of gov't procurement. Those retirements were mostly en-masse, entire fleets being cast off. The reason? They were just worn out. When you consider their duty cycle, it's not half what Amtrak sees. A Silverliner or M2 doesn't move all night and also sees less runs mid-day, where a long distance train runs all day and night.
So to put it in perspective, you have a small fleet of 22 cars with varied background (you have 22 1-car fleets for some purposes) from 1950-ish running all day and night. Compare that to a fleet of 1970-ish M2's that were just retired, and they ran mostly at rush hour in a large fleet. They were still uneconomical to retain.
Things wear out. It's a way of life. Some may find new homes, but statistically, many don't. It's a good thing, because that frees up resources to keep a few in solid state of preservation rather than tens or hundreds in crummy shape. Consider the South Shore or North Shore cars from the 1920's - many were saved, few are in decent repair. Quite a lot are rusting away under tarps in fields.
