We have a more service sector based economy and if you knew even an iota about how economies work you could it out - the link with productivity. The BOE seem to think its mainly due to poor worker productivity.
But Globalisation - now if you are saying the reason for low wage growth is increasing trade liberalisation then that is an argument against Brexit?
WTO anyone?
You don't mention access to cheap labour, a result of globalisation and the driving force to lower wages. We were a service sector based economy long before the wage stagnation we've seen.
