It began years ago with the decline in manufacturing production, in the car, ship building and many other sectors. The refusal by unions ( who were regularly on strike) and governments meant that when investment and automation were required to maintain efficiency and produce a high quality product the U.K lagged behind.
Meanwhile, motorbike, car, armouries, ship, rail and plane production deteriorated and excelled in Japan, Korea and other European countries. All the support industries, steel works, machine shops, transport, etc. also declined.
Sad but true, we don't make much now and buy it from elsewhere. The service and finance Industries are all easily movable (hence Indian call centres)
Now that these Industries have been gone generations there is nobody left to passion skills.
I also agree that the low wage culture supported by tax credits has not helped with investment and efficiency.
