You're linking to employment. Like manufacturing, these industries have been significantly automated and mechanized. So yes they have been employing fewer people. Corporations can't move the land and minerals and oil and gas offshore though, so those industries have not been killed. The cost of labor didn't kill them. That's despite all these minerals and petrochemicals and farmland available all around the global south too.
