That's never been true (at least since the first chips or components). A lot of my Shenzhen orders have to wait on international airfreight on US-made chips because the ones I spec'd (basically the only ones that would do the job) are US-manufactured and warehoused.
Recommend you look at a world map of Intel fabs. Or Micron Fabs.
Lets be realistic.. components meaning 0805 capacitors and resistors, small digital ICs. I can almost guarantee those aren't made in the US... and are WAY cheaper on a site like LCSC.
While I agree in principle that most chips aren't made in the US, tons of 0805 capacitors and resistors are made in the US. Vishay does a lot of that here, as well as a few other manufacturers. Mouser lists country of origin and you can search that way.
Lots of use cases are more speed than cost sensitive. I.e. yes if you are paying a bunch of engineers in Boston who graduated from MIT to work on robotics $165 is a rounding error if you aren’t producing at scale.
Basically anything aerospace and defense related will care more about speed and compliance than cost.
A supply chain that also comes from Shenzhen... last time I checked, North America doesn't make chips or other components either.
