"I accept that if we vote to leave the EU there will be a short to medium term recession" This may or may not happen - no one knows.
Except most economic sources say that an exit from the EU would most likely cause a recession. The Economist, PWC, HSBC etc all have researched it and come up with the result in a recession and in the long term would be adverse for the UK economy.
"However, using data available, the EU block of countries are a shrinking economic block. "
Which is to fundamentally misunderstand the "data" the EU economy hasn't shrunk This isn't to sayit's larger than it was in 1980 in current prices and in constant prices. Europe's smaller share of world output is because of the rise of other economies especially the BRICS countries.
My question is why would we want to get into even closer political union with a failing block of countries? Trade with them, yes. Controlled by them, no."
But we have a larger wieghting on our vote at the EU than many of these small countries. As said before in EU votes the UK is on the winning side 90% of the time. . Also Cameron won an agreement that we would not have to be involved in ever closer political union.
The points about immigration, sigh, again to have to say that economically immigrants from the EU are net fiscal contributors, which means that they pay more in taxes than they take out in services. Even if you sent all EU immigrants home the pressure on services would not be reduced greatly because most are young and don't have kids so therefore don't use most services. The migration bounce factor also comes into play here because most go home, for example immigration from the EU8 countries this year was about 74,000 but a net migration factor of about 45, 000 which means about 30,000 people went home.
Three: Your point about "unskilled" labour is understandable, you say about driving down wages for British workers. But 65% of the EU 14 workers that are graduates and about 25% of those who come from the EU 8. So the level of "unskilled workers" is relatively small when you consider that 1.4 million immigrants are from EU8 countries, so around a million workers are going to be considered to be "unskilled" but then we have to take into account all the plumbers, brick layers etc that are from these countries so then you get an even smaller amount. As a % of the workforce their influence is very small.
Which brings us to the house price situation. There are about 3 million EU immigrants in the UK, so about 4 % of the population, again they aren't the driving factor determining house prices. The number of new homes needed each year has been about 250,000 for a few decades, but we have consistently built less than that, a chronic shortage of housing in the areas in which there is demand is driving the house price rise, along with the availbility of cheap credit.
Bronze's health tourism point is fallacious too because the nbumber of people who come to the country aiming to take advantage of free healthcare is ridiculously small.
I understand people's concerns for the future, but you really have to think that if you are backing brexit then you are contributing to making the future worse. If we negotiate an EEA style trade deal then we will be like Norway, still paying for the EU and following regulations, with the four freedoms still in place. If we don't have a deal like that it is likely that UK firms would struggle to compete with EU ones in terms of trade because we will have tariffs and quotas of what we can supply, we would not be included in EU trade deals and having to negotiate our own with a much weaker position of negotiation. We might be the "5th" ( 6th actually) biggest economy in the world but France and Germany and the 5th and 4th, California alone is the 8th. The size of the economy doesn't give you an advantage, the amount of trade you do with others does. Outside the EU this would be diminished, especially in our services indusrty. Car companies for now have said that they would stay ( bit 88% say staying in the EU is important) , but if tariffs are placed on British made products in future that might not be the case.
I'm not going to tell you that you are wrong, I understand that people are concerned about the EU, but hopefully some of the things I've pointed out will help allay them.
