And you will have to pay the increased cost unless you can live without anything from China.
My guy, if oil is 250, people will die from starvation because fertilizers are too expensive to use in India/Bangladesh/Africa. I.e if a customer dies they don't exactly buy things anymore.
People will stop driving in the US, and yes people will stop buying things that they can't afford, including from China; even while the refiners keep gouging profit. Feature, not bug, of the US system. I'm all for fleshing out the gory details of how the US society continue crumble as a result of this, but that is a 5-10 year process that's already underway.
The rest of the world operates on capitalism where yes, the poor will suffer from not being able to afford shit. Affordable childcare and healthcare is already a luxury in the US - is it difficult to imagine that a steak will become a luxury? What about cheap TVs from China?
If oil is at 250, a big portion of oil demand at 100/120 will have gone away (i.e they cannot afford it, or their SE Asian economy imploded) such that oil via the ocean is readily available again for the richer/better off countries. I.e you would never bother to ship oil via the train because you can just buy it at the going price.
If the condition of 250 oil is because the US actually blockaded Chinese oil for 6 months, then as I've said many times before rare earth ban + blockade of Taiwan would be likely the response in which INDOPACOM gets to find out how DF missiles cooks them.
Shipping oil from Iran via rail is like virtue signaling.
