Since 1973? Why do you keep saying stupid shit?
He's probably under the mistaken impression that the electronics industry pretty well left the United States about that time, due to ecology laws being pushed by Democrats.
Some still remains, but manufacturing primarily has moved offshore.
Most went to Japan, which makes sense, since Japan has been good with lens manufacturing for some time (Zeiss lenses are some of the best in the world). Electronics and lenses (and later lasers) fit hand in glove.
Today, most electronics is manufactured in Japan, South Korea, and Taiwan (which specializes in custom processors, used in game console, automotive use, etc).
China manufacturers electronic mechanicals (primarily computer cases and associated hardware), solar panels, batteries (particularly lithium oxide), LEDs, and PC boards. They also do final assembly work (such as, until recently, iPhones).
China does provide shipping service for much of the eastern Asian coast. Another big shipper (though not as big as China's) is South Korea.
Japan manufacturers displays, stock electronics (including standard chips, resistors, inductors, and capacitors, transistors, memory, transducers, connectors, and switches), and batteries (particularly nickel-cadmium and dry cell, and small lithium oxide such as coin batteries or N batteries). South Korea manufactures displays, linear custom chips, memory, some vacuum tubes (yes, they are still used!), transducers, transistors (particularly power transistors), some switches, and connectors.
Other products of China include textiles, fireworks, steel, machine tools, power tools, custom hand tools, chemicals, and of course, shipping containers and ships.
Other products of Japan include textiles, fireworks, precision tooling, video games (Nintendo, Sony, Atari), consumer electronics (Sanyo, Yamaha, Sony, Fuji), automobiles (Toyota, Subaru, Honda), kitchen appliances and knives, motors, and personal robotics).
Other products of South Korea include textiles, consumer electronics (LG), automobiles (Hyundai), precision tooling, and motors.
The States are big manufactures of textiles, food, lumber, trucks and other automobiles (Honda, Ford, GM, Subaru, etc), software and cloud services, industrial robotics, memory, chip design services, stock chips (microprocessors and other LSI primarily), medical technology, equipment, and supplies, plastics, and video games (Microsoft, Nvidia, Steam), fireworks, and medicines.
There is a general opinion that the States don't manufacture anything anymore. That is quite untrue.
