Daphnedill - regarding immigrants. "British employers are making money from them, because they work hard, fill skills shortages and often accept worse pay and working conditions."
You said it. That is EXPLOITATION. The EU encourages migration and it drives an austerity budget. People all over Europe are having to compete for jobs and the ones who'll take the smallest pay-packet and longest hours are employed.
How some of the liberal left supported the EU and this capitalism in it's worst form is beyond me. These exploited workers, many of them in the UK, have no Union representation either.
It's disgusting - just a few notches up from slavery and supported by of all parties, Labour, who wanted the flood of immigration to continue, so bosses could get rich on the back of it! 
This was one of the reasons why most of my left-wing Labour supporting friends wanted Brexit. This would have continued. No wonder big bosses wanted us to remain in the EU.
