To go into the background, a little rambling tour of the territory is perhaps in order, so here goes....
You see, I don't care about "experiential" much. As long as a Sleeper is made available without the "experience" at a lower cost, I am all for the "experiential" for those that need it at whatever they need to be charged for the experience.
As long as it was available, I took the Slumbercoach which is the sort of thing I need mostly, and it did not add the cost of the experiential since meals were not included in the fare for it. Sadly they went down with the potty fiasco.
As far as I am concerned the way Sleeper service fares are structured these days, it is a means for the likes of me to subsidize the "experiential" for those who are unwilling to bear the cost of their experience. I know this is probably not a popular position specially in a group tilting "experiential". But hey it takes one of each kind to make this world.
The reality though, is that LD passenger service is so minuscule and Sleeper within that even more so, that it is probably unrealistic to partition the market further with myriads of levels of service, so in practical terms perhaps this is all that is realistically possible. The cost of not having a system that is not really large enough to be quite viable yet, and which has failed to keep pace with just the population growth in terms of ridership. So the train lovers like me would now basically have a train at virtually any price. At least I certainly behave that way!
Historically, after the fares were raised by very significant amounts ostensibly to cover meals, the transfer rules were set up such that provably a larger proportion of the additional fare (which was supposed to be for covering meals) was plowed back into the transportation side, and an inadequate amount was assigned to the F&B side to sustain the Diners (that is how we got where we are). They could have transferred a fixed proportion of the fare to F&B and F&B would have gotten more money overall if done right. Instead they decided the complex method of actually transferring only the menu price of actual food consumed, as if people eating cheaper items would require fewer OBS personnel to serve them. The whole thing was a typical Amtrak and DOT/Volpe Center engineered cockup. At the end of the day all of this is direct consequence of making "profit" more important than "service", which has been Amtrak's Achilles heel since day 1.
