I think the OP has had a hard time here. It's fine to think about how this will affect your family. Everyone votes with a different set of priorities.
I will be voting out - immigration will continue, but it will be controlled. We will have a better idea of who's coming in. We need to be able to choose people based on skills. Cameron is deluded when he says EU economic migrants can come here, look for work for 6months and then return home....they stay illegally, live under a bridge, or 10 to a room and work for unscrupulous employers for below minimum wages. They still earn more than if they were in their home country. The government does nothing to chastise the businesses that do this....(unlike in France).
I want stricter border controls in this uncertain and changing world, not a quick glance at your passport as you push through "immigration control". Even though we are out of Schengen, it appears we have a crisis on immigration - it's been a hot topic since 2004 when Tony Blair first opened the doors to an estimated 13,000 Poles - how many million came?
I understand that the Remainers think staying is the safer option, to vote for the status quo - but Cameron cannot tell us what the EU will look like in 1, 5, 10 years time. The EU economy grew at 0.3% in the last 3months of 2015, youth unemployment in Southern Europe is 45-50%, there is deflation - not a recipe for economic growth. Why stay hooked up to that - it's like running through treacle - why not look to the the world - currently we can't negotiate trade deals ourselves, the EU has to do it.
Whatever we vote we are not voting for the arrangement as it is today. For sure it will be an even bigger union with 5 more countries being readied for accession - will Turkey make it when they have ALL the cards against Merkel in this migrant crisis, which is kicking off again? Ever closer union is the aim of the EU, although with the emergence of the right wing, sadly that is the way the people will vote against it. Euroscepticism is growing in the EU. No one knows what it will look like in the future.
Is Cameron's "re-negotiation" even agreed - they are currently proposals - they haven't been put to the vote in the EU - that's happening after the referendum! What happens if they are rejected?
And finally, our public services and infrastructure cannot cope with the current population levels - how will our children afford to rent/buy? All my neighbours 20 something children are living at home with them. The new housing development near me has lots of houses, but no doctors, schools, shops - everyone has to get in a car to go anywhere - the roads are jammed. There are no reliable and regular bus services, the library has been closed, potholes in the road not fixed and the budget from the Westminster government cut again. All planning applications are waved through even if opposed in the rush to build. With 50,000 new homes per year in London promised by Sadiq Khan, what will the air quality be like with the additional cars this will bring? What will the roads be like, what will public services be like, how will the sewers cope!!
People are rebelling because they feel it is all out of control.
