All the technologies above were developed years and or decades ago. Boeing planes have had door plugs for decades, since they started making different models of the 737, needing different numbers of doors for evacuations--not having to taylor-make barrels of the aircraft. That failure, in particular, was the result of not reporting modifications made. Blame Spirit Aerosystems. "Death to America" was happening back in the 70s and 80s, too.

No, investing in American manufacturing will only help, especially when Russia and China decide to invade other countries and we find ourselves relying on US technology, like when SpaceX took over flying astronauts to the ISS--no more handing hundreds of $millions over to Roscosmos.

Intel Corp. needed the financial incentives to build chip plants in the US, and now they have it.

For the golden example of improvements to technology, you can look at LED light bulbs, that last ten times longer and use 1/10 the electricity, for arguably better light. Nobody was going to build an LED bulb until the government came up with the "L-prize"
