Re: Whose agenda?
Why was Greece forced to sell state assets? Because by doing so they received something called money which can be used by the State to pay pensions, the interest on loans and lots of other wonderful and worthwhile things that all Govts need to do. Kind of like why you have to sell your house when you can't afford the mortgage.
The EU does not have directives that force privatisation it does have directives that strive to create a level economic playing field for businesses. State owned business skew that playing field as they can keep going back to the Govt to get money when they lose money undercutting other businesses (Air France was a great example of that).
As for undemocratic, compared to what the House of Lords? The Council of Ministers contains elected officials from every Member State and at the end of the day those elected ministers can decide whether to suppor or reject the suggestions of the European Commission whch in some ways is like the House of Lords being made of personal appointees of the relevant member states leader (Dave Cameron in the UK's case). And then MEPs. Not sure where your fourth chamber comes from because last time I checked the treaties all EU law goes from Commission to Parliament to Council of Ministers.
As for being right wing neo liberal agendas, have you looked at the UK govt recently? In fact the biggest threat to the NHS remains the British Govt not the EU or even TTIP. But then if you are American, the EU is the communist replacement for the old USSR what with its social welfare and health for all ideas.
The reason why immigration is the focus is pretty simple. No one knows what will happen if the UK votes to leave (well other than the economy will suffer from a short to medium shock of major consequence for business and citizens alike) or stay (other than things will go as before). Therefore the Brexit bunch have identified something simple to understand, "the EU lets in lots of foreigners and they are all coming to the UK" and then complains when those who want to stay say "its more complicated that that".
I do agree about it not being an issue of "little-Englander" mentality though. It is significantly more complex than that. Europe is riven with massive problems not all of which the UK is immune to. Those cracks need to be addressed, if we are outside we cannot do that, if we are inside we will have to use diplomacy (not somethng we are very good at) and all the while we have the media constantly making out that everything is simple and can be fixed with a quick wave of a magic wand (talk about dumbing down the population). Whatever the decision on 23rd June, the consequences will be massive and no one in the media is telling anyone the truth about that.
