What remainders are in fact voting for is to continue the journey that the founding fathers of the EU always wanted - a political union of all member states with one currency. A government based in Brussels with regional assemblies in each country. Brussels will determine tax and spend rates for each region. Everything the EU machine does is by stealth. No doubt when the time comes for Britain to make a decision as to whether to join this political union, the same debates and arguments that we are having now will crop up again. I will be voting "out" tomorrow although I expect the Remain camp will win. At least when I see the smirking face of Jean Claude Juncker on Friday morning it won't be because of what I have done in the vote.
The one thing the EU doesn't involve itself in, is member states tax rates and they can't do so, as they need member states to have the flexibility required to manage their own economies and stop the Euro turning into a disaster (the currency, not the football tournament).
There's little chance of us adopting the Euro any time soon either, we can't be forced to do it and over 80% of the UK population don't want it.
