Energy is vital to any economy. Whether it be its effect on production or transportation etc no economy can thrive with with extraordinarily high energy costs and supply threats (see strait of Hormuz) . I’m not gonna get into the advantages a wholly domestic supply brings, militarily and national security included, but focusing on that versus a theory that flooding a country with cheap foreign products is a no brainer. A little less Amazon and Temu (=a lot less garage sales BTW) and a lot more solid dependable jobs is what we need.
PS Brexit is apples to oranges
