How so?
I can't think of one possible detrimental effect it will have to me or my family....Perhaps you would care to expand on this?
I did post up some stuff on page 1 or 2 of the thread, but I am happy to go over it again.
Cost of goods. Goods sold in the EU have to be sold at the same price in whatever country the are purchased, subject to local taxes. This includes flights BTW. I certainly can remember the old days when things like cars and air travel were more expensive in the UK because it was deemed we could afford to pay more. Without the EU's protection, airlines and holiday companies, for example, could charge us brits more than our EU counterparts for flights and hotel rooms because they were booked in the UK.
Deregulation of EU airspace. The deregulation led directly to the formation of the budget airlines. Out of the EU, there would be no guarantee that certain routes would be given to the UK based airlines.
Mobile phone and roaming charges. Again, the EU has done a lot to bring these down to an 'acceptable' level. Out of the EU, the phone companies would be free to sting you for using your phone in Europe.
Medical bills. By signing a simple form you can get free medical care in the EU. Without that you would need to buy insurance.
Free movement within the EU. Although many cite this as a bad thing, it also means we a free to travel, work, study or retire anywhere in the EU. If you don't want to pay the UK tuition fees, you can study in an EU country where they charge less or where it is even free. There would nothing to stop a country from charging you to enter its borders, as I believe they still do in Turkey. It would be more difficult to work in the EU, EU jobs for EU citizens.
Clean beaches. Maybe a minor thing, but for a long time the beaches in Britain were terrible and no one was cleaning them up. And of course the same standards apply throughout the EU.
Workers rights. The EU has done loads to improve the work life balance from bringing down the maximum working week, introducing minimum holidays, breaks, parental leave and the rights of pregnant workers. I seem to recall all the scaremongering that went on at the time when the EU wanted to bring down the maximum working week to 48 hours and that it would lead to mass unemployment.
In my opinion, we are better off in the EU. We enjoy better consumer and workers rights, and cheaper goods and services because of it. I don't believe leaving the EU will lead us to nirvana and our home grown politicians are quite capable of making bad laws as anyone else, for example IDS and his welfare reforms.
I hope that has answered your question Callan.
