Well, it does make some sense that China's plan's to counter the US during an invasion of Taiwan would focus on nullifying America's main far-from-home force projection method, which has for decades been fighter planes and cruise missiles launched from naval assets 1000km plus off the coast of the target nation.
Since the US has been using the same overall strategy again and again for decades now, China would have had lots of time to develop counters for it, and it's not as if Chinese Engineering is any less than Western Engineering.
I mean, Russia too developed hypersonic missiles exactly to counter that very same American strategy. Now, Russia is well in range of lots of land-based assets of America's allies in Europe so it could be targeted by those, but that's not at all the case for China which America has to approach by sea, and that will be done with the usual Aircraft Carrier Group and hence that's exactly what China would have set itself up to counter.
America has long wasted tons of its military budget in things with tiny or even no Return On Investment in terms of additional effectiveness for every extra dollar spent.
In a sense the greatest enemy of the US is itself, in the form of the MIL and Corruption from the lowest levels to the highest.
I mean, notice the recent change in the budget for the military which this year removed the Right To Repair for the Military, something which does nothing other than hinder Military effectiveness whilst further enriching military hardware suppliers.
The way the money is misused and redirected to feather the nests of large military companies' shareholders and CxOs, as well retired Procurement Generals who move to cushy jobs in the very companies they bought overpriced items from and MIL-friendly politicians in subcommittees approving white elephant military projects, is sort of a twisted mirror version of what happened in Russia were everybody in positions of power was on the take and their military when finally faced with a proper adversary at the same technological level - in the form of Ukraine - turned out to be a lot less than it seemed on paper.
Also America went down a route similar to Germany in WWII when they went for tanks like the Tiger Panzer which were peak-tech and very costly to manufacture, which the Allies countered by just throwing lots and lots of not-quite-as-perfect yet much cheaper and faster to manufacture tanks like the Sherman at it.
America has the biggest military budget in the World by a large margin, but also outright wastes a huge fraction of it and pays top premium for small incremental improvements, so the results aren't as impressive as one would expect from just looking at money spent.
If you want to see efficient use of a military budget, look at Ukraine.
