High cost of large projects is certainly a general problem in the US, but it may not be due to labor costs alone. Here's a Bloomberg article that attributes it to "over-design, inefficient project management and misaligned politics." https://www.bloomberg.com/news/articles/2021-12-08/why-building-roads-and-transit-costs-more-in-the-u-s https://www.bloomberg.com/news/articles/2021-12-08/why-build...
I think it's entirely possible that in the US, where we have copious wind and solar resources and we've gotten bad at doing large projects economically, nuclear is not the best option. That says little about the rest of the world, though. And it's possible that small modular reactors would help even in the US, because while we suck at big infrastructure projects, we're not too bad at high-volume production in factories.
And that brings us back to fusion, because a lot of modern fusion designs would be more like factory-produced modular devices rather than large site-built infrastructure projects.

It anyway fails to address extraction cost, for which there is no plausible means to match renewables' near zero cost. By the time any new nukes could be brought online, capex and opex for renewables will have fallen far, far below even their most aspirational projections.
