Of course it should be built with products from the USA. I live in Texas now but am originally from Northern Michigan. Michigan,Minnesota,Pennsylvania all past leaders in the steel industry had their economies in the early 1980 ‘s devastated due to the decline and need for American steel related to the auto industry.
I have lived in Texas for almost 40 years now.
Personally this wall is a big waste of money and the tariffs are ridiculous.
They are going to still come here one way or another.
Our country was built on immigrants. My grandparents fled Lithuania in 1908 just ahead of the Soviet Union takeover. They came through Ellis Island. Subsequently my grandfather then fought for the USA in WW1 and was granted citizenship.
Some stupid wall will not solve the problems.
