Same with steel, or just about any other heavy industry you can think of.
All we build domestically now are Aircraft, Aircraft Carriers (because the Government supplements the ship-yard), Submarines (ditto), and entertainment. Cars are going away...we loose that and ALL of our consumer production is pretty much down to the cottage industry level.
And after that...it's all just an "import economy"...until the money runs out (and I can see the light from that particular oncoming freight-train now).
(SIGH)
Sucks having a brain and being an American.
