To elaborate on Barciur's comments:
1. Amtrak is *NOT* run like a "business", not even close (so please stop bringing up this nonsense of running it "as business").
It's "business model" is fundamentally flawed.
They have low-revenue LD routes that are subsidized by high-revenue shorter routes (Acela, Auto Train, etc.)
A "business" would immediately cut [at least some] LD routes (Sunset ?) with freed equipment redeployed
on CHI-DEN, CHI-MSP (even on AT) routes with higher demand at higher pricing points.
Also, most businesses give DISCOUNTS to their best customers (which in Amtrak case would be Acela's and AT's
passengers as they pay the highest fares already), yet Amtrak keep increasing Acela's and AT's prices through the
roof. And why not increase LD fares through the roof ? Because then nobody will ride these trains, as there is no
"natural" demand for cross-country travel by train.
2. Amtrak does NOT have a competition, so it acts as a "natural monopoly".
Natural monopolies should NOT be allowed to increase prices uncontrollably (it is called "price gauging").
Public utilities (the other natural monopolies) provide a good comparative example.
People actually need electricity much more than they need Amtrak travel, and most people actually
CAN AFFORD doubling or tripling their utility bills, yet it doesn't mean that this is the right thing to do.
Regulators will not allow this to happen, as utility rates are modestly revised once every few years, and a hearing
is usually conducted.
Same logic should be applied to Amtrak -- especially since it gets public subsidies, it's fares should be
REGULATED by a commission and not allowed to increase uncontrollably (even if there exists a large demand
on certain routes).
3. Sometimes it seems that the main point of Amtrak's existence is for the benefit of its management and
employees and not for the travelling public. Customer service ? Amenities taken away ? Costs of running Amtrak
(fuel) may be increasing, but the price increases recently thrown on Acela and AT routes seem way in excess
of the general inflation. It seems that paying passengers are being asked to cover bigger and bigger share of
Amtrak's inefficiencies than in the past. And, as nice a rail journey can be, it's still NOT the *TRUE LUXURY*
experience, so charging the "true luxury" prices is absurd. Wait until [sleeper-riding] price-insensitive public
on Auto Train dies out, and younger people (currently riding coach) balk at the price increase and hit the I-95 again.
