In winner-takes-all markets, it becomes worth it to pay 10x for 10% better.
The reason in workplaces people don't hire somebody else at a fraction of the cost isn't because American workers are 15% smarter than non-Americans. It was just very difficult to have exactly 1 remote worker on a team, language barrier, international laws, etc.
In my experience people generally aren't willing to pay double the salary for 15% better work. They will however pay market for domains where nobody else is qualified.
Actually, companies are already willing to pay double for 15% better work - the proof is in what SWE salaries in America have currently become.
Companies are pretty much paying at the frontier of marginal improvement (not returns, which again, are hockey-stick) - i.e. it's not like paying 800k will reliably hire someone 15% better than the 400k that they're currently paying.
At this point, the limiting factor is their reach-out and interviewing processes, and the ability of the brand name to attract talent (OpenAI can actually get better talent by paying 800k; Microsoft would not because they're still Microsoft and some people would simply never respond to a Microsoft recruiter even if they lead with "this role pays 800k").
American software has flip-flopped between rushing to outsource and realizing that outsourcing is a bad idea. LLMs (plus US work visa policy headwinds) are simply what triggered the current flip cycle.
There will always be a market for the most intelligent model. Keep in mind as well that something like Fable doesn't have to be cost effective on its own. Fable is Anthropic's way of building datasets for smaller more dense models, which is viable on its own as a method of success. These large labs are constrained by their dataset more than anything else, and these expensive-but-intelligent models create some of the best data out there.

To be honest, I use both daily and feel no difference in this case
A few percent better on tests like this translates to extreme real-world differences, and that's not even taking into account how benchmaxxed DeepSeek models tend to be.
It's fine for slow tasks but if you need something done quickly, I find that DS just spents at lot of time thinking.
After using Claude for the first time for about 2 weeks, I've been impressed by the quality and speed of Sonnet 5.5 to do code changes (~20 seconds). Meanwhile DS would have taken 2-5 minutes.
While they made, hands down, the best models, their 100x price for few percent better is completely made up, and I think it will end up bad for them
