Why did Marshall Plan aid not fully modernise British industry?

How was Marshall Plan money spent in Britain, and why did Germany appear to modernise manufacturing more successfully?

Britain attempted modernisation, but job-loss fears and owners' reluctance to interrupt production made investment in new machinery politically and commercially difficult.

The viewer asks why Germany appeared to invest postwar aid in new manufacturing tools more effectively than Britain. Britain did try to modernise, but a strong labour movement feared that new technology would eliminate jobs. Owners also had reasons to avoid interrupting current production, because installing new machinery meant not building goods during the transition. The answer assigns responsibility to the interaction of labour and management rather than reducing the outcome to one side's failure.
