I've given you the arguments, higher wages, controlled immigration, a more democratic system of government, less risk from Euro collapse, and we'll still be richer than we are now if we leave according to the treasury.
Nope those aren't arguments - just a wish list, which won't be delivered by leaving the EU.
So to nail each one:
higher wages - evidence please - all the evidence I've seen suggests lower wages as the economy would do worse if we left rather than remain leading to unemployment and suppression of wages in the wider economy. Plus also you need to consider inflation - again the expert opinion suggests upwards inflationary pressure if we leave (in part due to weakening of the pound making imports more expensive) and even if wages remained the same in absolute terms they would be reduced in real terms due to the greater increase in cost of living.
controlled immigration - but we already have that for virtually all countries in the world - so are you saying that the approach for migrants from (for example) India, or Pakistan or Argentina is perfect. It is completely under the control of the UK government (in theory). So why then has the 'controlled immigration' risen proportionately to pretty well exactly the same extent in the most recent data than the 'uncontrolled immigration' from the EU. The reality is that it is market forces that really drives things - so a government can 'pretend' it has control, but if we need migration to fill vacancies that will happen under any system and any government, because otherwise the effect on the economy and public services would be dire.
a more democratic system of government - the EU is arguably more democratic than the UK government in that two of its elements (EU parliament and Council of ministers) have a democratic mandate, whereas we have only one - the House of Commons, with the Lords undemocratic. And our system of voting in Westminster elections leads to the current situation where one party can have all the power when 63% of the people didn't vote for them. I'd be worried about vesting more and more power in Westminster, noting that we already have one of the most centralised government systems around. I think that the EU helps to provide some checks and balances to mitigate agains the worst excesses of Westminster.
less risk from Euro collapse - we aren't in the euro and therefore aren't required to provide any direct bail out to the euro (as we didn't in 2008). But of course we will be affected economically by a eurozone crash, and just as much if we are out as in. But leaving will weaken the UK economy and also have a ripple knock on effect on the rest of the EU, weakening them too. So Brexit makes the chance of a euro crash more likely, doesn't alter our exposure to it but our weakened state will make it harder for us to ride the storm if it comes. So bad all round.
we'll still be richer than we are now if we leave according to the treasury - we've done this to death - the relevant comparison is whether we'd be better off if we stay compared to if we leave and we would be. And actually the Bank of England and others are suggesting that negative growth is a distinct possibility following a Brexit vote.
