Depends on your political opinions of course, for me I'm a natural leave voter for reasons such as:
- A significantly reduction in industry red-tape, which is underwritten by EU law. This would reduce business costs significantly at little real world cost
- A reduction in pointless barriers solely designed to protect EU industries (the typical example is chlorinated chicken) but there are others preventing the importing of perfectly good produce via protectionist standards that
- Tariff free trading with the rest of the planet for everything. As a nation with a small manufacturing industry external tariffs on the rest of the world are counter productive and keep prices artificially high. The current external tariffs are designed to protect the manufacturing nations in the EU but it is somewhat at the expense of the non-manufacturing nations.
- If we accept that as a country the UK population does not want net immigration into six figures, I'd prefer this amount be hand picked dependant on what the country requires. If we are short on Doctors I'd prefer we "import" an Indian Doctor over a Hungarian Receptionist
- Governing with consent. The further away from a location that decisions are made the less chance that these decisions are being made in the interests of the people in that area. Laws, regulations, rules and standards that have to be made taking in consideration 28 member states can never be in the specific interests of every country, let alone every region
- Democracy. Irrespective of the ability to vote in MEP's (low turnout anyway) or the potential to veto, the system in general is not particularly democratic. Just like I'd like to replace the House of Lords and change the voting system in the UK to be more democratic; I also believe the EU needs huge reforms that I just don't believe will ever be enacted, given the disassociation of the EU from the people it supposedly represents (this is true of Westminster to a lesser degree)
- The difference in values across EU nations. I can't see how a political union can be possible whereby you have nations with such divergent values and beliefs. It's hard enough trying to run a country with the values of people in the South compared with the values of those in the North (I believe in far more regional powers); let alone trying to run a union with countries as liberal as Sweden alongside countries on the other side of the spectrum such as Hungary
- The future. Ultimately I believe the EU will have to harmonise tax laws. For someone who believes in the Singapore model on tax policy my view is the EU model of high taxation will ultimately make all citizens poorer.
- Prosperity of the third world. Not penalising the third world in terms of trade is the key method in my view of reducing world poverty and equalising prosperity. I believe the EU has blood on their hands in feathering the nest of their own wealthy countries at the expense of far poorer African, Asian & South American countries.
- Subsidy. If you believe that the EU is great for all members, then why do the members not get out what they put in? Why should the UK pay more in that it receives out if the union is mutually beneficial? I find it difficult to understand money London generates being used to pay for Scottish infrastructure... Let alone Slovenian (and if Slovenia why not Somalia?)
However I also am aware that the benefits are somewhat theoretical and also economically difficult in the short term. It's dependant on whether we elected the kind of government that would (enact some or all) slash red-tape, reduce regulations, slash taxes, ensure full tariff free trade across the planet (even at the short term politically uncomfortable expense of some UK industry), enact policies allowing greater regional powers and/or promoting the purchasing of goods from poorer continents. However it's easier to elect that kind of government in the UK than it is to not only elect that government in the UK, but also then need to have your government successfully lobby it within the EU.
Truthfully though I'm somewhat sick of it all at this point.
