Routes with transition dorms and two or three full sleepers are in some cases down to a single sleeper and no dining car, but you're worried that being "hyper-focused" on sleeper availability and "high quality" dining might somehow preclude essential service? I can count the number of times I've seen my trains run out of coach seats on one hand, which is the same hand that can count every time my trains did not run out of sleeping compartments.
No one is disputing the well-documented issues Amtrak is having with equipment repair and staffing that has limited the availability of equipment.
Nevertheless, the document posted states that Amtrak is an essential transportation service for flyover states and
specifically notes the cost of other forms of transport as a reason why Amtrak is essential. Passenger data tells us how people are using these trains - they are using long distance trains essentially as regional corridor trains, in lieu of actual regional corridor trains.
From this, one can reasonably infer that if cost is a concern, people living in flyover states are not looking to use sleeper services en masse. In fact, the data spells this out: for each of the four western trains (not including the Texas Eagle, just the Sunset Limited), the segment with the highest revenue is terminus-terminus. This does not suggest that the majority of travelers in Minot, ND are using sleepers to travel to West Glacier, or any other midpoint to midpoint journey you want to put forward. Rather, it suggests there is a segment of the American population that eschews air travel for many reasons readily pointed out on these message boards, wishes to avoid the rigors of coach travel for multiple days, and has disposable income to afford sleeper berths. Of course Amtrak should cater to this market, but we need to be realistic about what that market is vs. coach passengers - the actual majority of Amtrak passengers.
Of course, the data is limited by induced demand. Maybe there are many more people who wish to travel in coach, or sleeper, but there is not more availability/affordability of seats/berths. But we would only be guessing at that point without any hard data.
Empire Builder: most trips in coach are 500 miles or less. Most sleeper trips are 1000+, with the majority share of 2000+.

To be honest, what irks me as a non-sleeper passenger (I have used business class on the LSL, in fairness) is using "needs" of coach passengers as justification for more sleeper services. I get that the majority of posters here are sleeper passengers - but as I stated originally: what is the point of Amtrak? Essential service? Luxury service? Somewhere in between?
