On Saturday I went to my local Food Lion and by chance met a new check out clerk. Turns out she is a 50 YO college educated economic refugee from east Tennessee. Her mid sized town used to make cars, electronics and had a huge lithograph printing operation which are now all off shored. She had worked in a bank there in a supervisory role. She says the town is now a basket case. She left her house and stopped paying here mortgage, threw the keys in the door and slammed it shut, walked away because she couldn't sell it. Now she makes $10.00/hr at a Food Lion in central VA. Ain't globalism great?
Trade is in fact as you say, great.
I don’t know what city you are posting about but it was not able to compete, so the industry died. Capitalism is about competition
Socialism is about artificial industrial preservation.
