I recall in the early days of Walmart they had little stickers on items made in the USA and proudly advertised such. Then came all the Chinese crap into the Walmarts and the Made In America thing just vanished.
If we go to war with China, maybe Walmart will vanish. Maybe not, but they will be forced to sell anything but Chinese. Their prices will go up and they will be less competitive with smaller stores.
Same here.
