 From the mid-1970s, the Welsh economy faced massive restructuring with large numbers of jobs in traditional heavy industry disappearing and being replaced eventually by new ones in light industry and in services.In the late 1970s and early 1980s, Wales was successful in attracting an above average share of foreign direct investment in the UK.However, much of the new industry was essentially of a "branch factory" ("screwdriver factory") type where a manufacturing plant or call centre is located in Wales but the most highly paid jobs in the company are retained elsewhere.
