The EU is not responsible for the level of wages and/or cost of living in differing emerging/new EU countries. Those countries who've joined in the past 10 years or so aren't just going to alter their salary structure to suit the UK. And the EU certainly isn't facilitating that.
A 10% rise in non-skilled EU workers coming to the UK would result in a 1.8% pay drop, according to the Bank of England (the equivalent of being paid £7.44 an hour as as opposed to £7.50 an hour) - which is vastly different from 'driving wages down'. Across ALL sectors of working migrants, there is no evidence of any wages being driven down.
If you think that the farming sector hasnt benefited from cheap labour from elsewhere then your daft and the consequences are obvious.
You cite 1.8% drop in wages on 10% increase on foreign unskilled workers, well in 2014 the unskilled workforce was 16%, which in itself is a wide brush stroke of industries I suspect the farming industry has quite a unique version of statistics that would multiply that effect.

Why would any wage deflation at the very bottom when we would all like to see wage increases be deemed favourable.
