There are probably several factors at play here. First, not all of the parts are necessarily produced in the USA - the PCBA is produced there, and the parts are assembled there, but the parts themselves are likely procured elsewhere. Even still, this greatly complicates the kind of supply chain attack this is meant to prevent, because you have to compromise individual components that you hope will end up in the device you're targeting. Second, they already had these facilities in place in the US for prototyping purposes. Thus, the up-front cost investment for setting up a facility in the US is much lower than usual, so they can set a lower price than others might be able to offer. Third, there is probably a capacity constraint at that facility; the price chosen was likely selected to suppress demand below that threshold, not purely based on relative production cost. Finally, although I have only limited experience (n=2) with cross-shopping electronics manufacturing between the US and China, a 3x overhead is actually substantially lower than I would expect; we were seeing ~6-10x increases for manufacturing and assembly. This could be because their production facility (which, again, already exists) would otherwise be sitting idle. I can't speak to the health of their business (a sibling comment suggested this was a "money grab"), but the numbers seem pretty reasonable for what you're getting, overall. Note that this is not targeting the same crowd who buys "Made in USA" t-shirts to support the local economy; the audience is more likely to be security wonks who are already concerned about supply chain attacks.
