The cost of Ca HSR has gone up to $98 billion. There is no way building even 6 airports could possibly cost that much, and you can build the airports when you need the capacity one at a time and airports support travel to anywhere in the world, not just the handful of other cities in California the rails connect to.
So California could build 5 huge earthquake proof airports in the middle of the ocean including sea wall and bridge for the cost of HSR. It just makes no sense. I'm not opposed to rail or high-speed rail. But the places where better public transportation are needed are mostly in the US North East where density is much higher. Existing rail infrastructure is crumbling in the North East while California asks for Federal money for white elephant boondoggles like Ca HRS. It's infuriating.
Much of the cost increases you see in figures like those quoted for CAHSR are related to timelines.
First, projected infrastructure project costs in the United States are usually quoted (by agencies) in year of expenditure dollars, which means projected expenditures for each particular year are literally inflated. If you push a project back 15 years, you can easily see double-digit percentage increases in quoted total expenditures. I don't know the exact figure but AFAIU this is very much the case with CAHSR--a large fraction, and perhaps even a majority, of nominal cost increases is related to inflation adjustments as the timeline keeps getting pushed back and stretched. (Of course, that still leaves a large component that isn't.)
Secondly, pushing back timelines incurs all sorts of additional real costs. For example, you have to extend supply and labor contracts, which often means you end up getting less for your money because more people and equipment will end up sitting around idle for longer. You can also incur greater financing costs.
Also, I don't think any of the figures in that therichest.com link are inflation adjusted. AFAICT, they seem to just be tallying the year-of-expenditure or perhaps year-of-completion costs. This difference compounds inflation discrepancies even more. (There are other problems w/ those comparisons, too, such as that most of those airports were built far away from developed areas, but it's not worth going down that rabbit hole.)
Time is the themostcritical component in all large construction projects, public or private. Time is money isn't just a catchphrase. If there are any hand-wavy, magical solutions to the cost problem that can be easily applied, one of the simplest and most obvious is to finish projects as quickly as possible. Don't let them linger and get stretched out.
Unfortunately, there are often political and regulatory pressures that push things in the wrong direction. If political blowback causes timelines to be stretched out, directly or indirectly, cost increases become a self-fulfilling prophecy. After learning about the accounting methods for how projected costs are quoted, and in particular digging into CAHSR costs, I vowed as a voting citizen to never oppose a project once it got off the ground, even if I initially opposed it.
I think given the variation in costs for HSR worldwide, we need to consider the first point of discussion for CA (or US) HSR to be "why are the costs so much higher here?"
It's true that the costs are crazy high, but that's not true worldwide. That means that objections to CA/US HSR are initially (at least) really objections to the ridiculous costs, not the actual idea itself.
