Very disappointing, but I guess in a way not surprising.
When it comes to air travel, the public happily subsidizes the company building the planes, the runways, the terminals, the access roads, and the traffic control system, among other things.
When it comes to rail (or at least Brightline), we subsidize… basically none of that, in a lot of cases cases. Companies have to build the track, the train control, the terminals, and everything associated, save for rare cases like SunRail. If you're lucky, in the case of Amtrak, then some state subsidy comes up (in part of the Midwest, California, and the Pacific Northwest). But certainly not to the extent of air travel.
