Just open the borders and let the third-world openly travel and immigrate to the first world.
To the non-college working-class that these anti-third-world policies are designed to protect: If your job can be taken by a third-worlder, then that's YOUR fault. You were given the privilege to learn skills that third-worlders don't have, but you didn't take advantage of that. You are in effect, a third-worlder, and society has no responsibility to protect you from them.
We, as a society, paid thousands of dollars to send you to school for 12 years to teach you calculus and literature and world history and what not, only for you to get your ass handed to you by an illiterate third-worlder? And you expect us to protect you? lol good luck with that. Just the ability to speak English is a minimum skill that should prevent you from losing your job.
I'm saying the numbers are so astronomically off that there is no viable path to profit without public subsidy, for any theoretical future system, big or small.
In the US, "public transportation" means "transportation system owned by the public". This is opposed to "private transportation", which is owned by private entities.
All tranport systems are available for use by the general public.
Also, the MTR infrastructure is government subsidized.
This was possible because cities weren't as developed as they are now. Property was cheap back then.
These days, the major expense of building a mass transit system is just buying property. And in cities, these properties are going to be already developed.
Right now, there are individual buildings in US cities that cost over $1billion, so grade-separated ground rail is not going to happen for cheap. That only leaves tunneling, which also isn't cheap.
It's not anywhere close to self-funding a real public transport system.
How do they expect to make money as a private enterprise if these are the numbers they propose?
Public transportation is supposed to lose money, not make it, hence the "public" part. It's paid for by tax dollars, because it is impossible for private companies to make money from it.
Even the private rail systems around the world are largely subsidized pubicly during construction, with only operations being privatized.
Die size is ridiculous, causing such high prices due to exponential costs associated with die size. It seems like an opening for AMD to use their EPYC Infinity Fabric interconnect for their next-gen GPUs in multi-chip modules with smaller dies.
OK I get that booster reuse cuts down costs, but the fact is the 2nd stage is still not reused, which limits the economic benefits needed to open new markets. We get a 50% reduction in costs, instead of the 95% reduction in costs.
You can get a 50% reduction in costs just by going to India for launch..
Is SpaceX going for 2nd stage reuse at all? That's going to be a lot harder than booster stage reuse, since you're returning to land at orbital velocity.
And then there's the whole issue of increasing reliability of the 1st stage for reuse hundreds (or thousands) of times needed for new business models...
OSHA has largely supplanted union safety regulations but the real issue killing this work is just workforce education.
We spend thousands to pay for 12 years of public education for each student to teach them things like Calculus and Geopolitics and Literature only for them to perform manual construction labor that an illegal immigrant from Central America with zero schooling can do?
