None of it. That all makes perfect sense and I totally agree.
What I don't get is the articles suggestion that its somehow unfair on UK workers that foreign workers can find jobs online.
I don't think the BoE are in the business of suggesting what's fair or unfair, just reporting on the state of the economy. You may have missed on of my edits:
"Besides, I'm pretty sure the BoE is talking about localised online job site e.g. a Lithuanian web site advertising jobs based in the UK in Lithuanian."
Would you agree that would make it unfair on British workers? If jobs aren't advertised in Britain or in English? Please don't suggest that fluent language skills in Polish, Lithuanian, Bulgarian and Romulanian are required to pick vegetables.
