Keep in mind that would put a huge dent in exports too which would put a huge hurt on the economy.
If the US wants to have its own economy it won’t be able to compete on a global scale.
In the past the US has been able to stay ahead of the curve with technology but now even thrid world countries have the latest technology.
In other words, our costs per hour are higher but through technology we could always produce many more units per hour.
Now other countries have similar technology but their cost per hour is still a small fraction of the US rates.
In fact because many factories are much newer in these countries they are actually better technology wise because they were built specifically for new technology while we are trying to convert/update old factories.
