You constantly ignore the overwhelming difference between immigration, which can be a good thing IF you can bring in the people that will improve things, and unfettered floods of financial migrants that just add to the already existing problems.
We unfortunately already have plenty of unskilled workers, to allow in more who will undercut wages while pushing up the benefits bill to pay out dole money is madness.
We are not dependent on the EU for jobs or anything else, they only buy a small % of what we make yet want to dictate every thing from laws to how we empty the f*cking bins, we buy more from them an pay more than world market price for the privilege.
The nine BILLION or so we save every year not being part of their little gang invested into British industry & infrastructure would transform this country, the politicians will be forced into this by a public long sick to the back teeth of there antics.
We regain our fishing grounds, control of our agriculture, justice system, borders , an we get to decide how we do things like empty the f*cking bins.
The EU is not just building up trouble for the very near future, it IS the ponzi scheme as Greece already found out, you ask about the uncertainty of exit, I say there is far more uncertainty staying tied into this mess, Hungary & Austria have defied the EU an closed their border, Poland has elected a right wing government who are refusing to take any migrants, meanwhile the EU do a deal of paying Turkey six billion euro`s an speeding up full integration into the EU for them in return for blocking a route for migrant ( Opening the door for 77million Turks).
