Blame the global economy and offshoring for that. GM at one time produced chips in Kokomo, IN by their subsidiary, Delco Electronics. Delco was bundled with a few other parts manufacturers spun off and named Delphi. A few years later Delphi declared bankruptcy and those plants were shut down and the parts were sourced offshore.
The huge parking lots where electronic products for GMs and many other auto manufacturers were produced with over 15,000 tax paying employees sit empty and crumbling with weeds growing through the cracks. Today GM is begging the Biden administration for seed money to produce chips domestically. Yeah, I'm aware it's just one of many pathetic examples.
