The right to study, work, live and retire anywhere in the EU that you wish.
Correct, if you wish to work anywhere in the EU I'd vote for remain. I'd probably vote remain if If was from Luxembourg and didn't want to be trapped inside a small, landlocked country. That is not a concern for the majority of Brits, and obviously it works both ways
Being able to holiday anywhere in the EU without visas.
With the obvious exception of countries which were behind the Iron Curtain or dictatorships, this existed before we joined the EU. You can enter Schengen from many countries (Japan, South Africa, New Zealand, Columbia, Tonga, Mexico and many more). It is laughable to suggest that Britain would be excluded from that list.
Cheaper flights.
Modern Britain is a free-market, non-protectionist country and would be happy to continue to allow free competition between airlines.
Cheaper phone calls.
It's amazing how high up the list this is! Another one of those things that is vital for people living near the border of Belgium, Luxembourg etc. In Britain where roaming accounts for a tiny proportion of phone use, these regulations are a subsidy for business travellers and rich frequent holiday-makers coming from poorer domestic users.
Cheaper wine.
Really? Wine import duties are generally domestic, hence why I still went to Calais for my wedding.
Cleaner air.
Perhaps lower CO2 but higher levels of nitrogen oxides caused by EU regulations favouring diesel for cars (unlike other developed economies) following lobbying by German car manufacturers. These emissions are not 'clean' and, unlike CO2, actually cause increased deaths right now.
Cleaner water.
National requirements exceed directive requirements. Why wouldn't this continue?
Cleaner beaches.
Fair play.
Equal pay for men and women.
Our Equal Pay Act 1970 beat our accession to the EU by two years.
Rights for temporary and agency workers.
Which lead to a perverse incentive to remove workers before they hit their 12 week point.
Better protection for workers with regard to hours.
Mandatory maternity and paternity leave.
Rights for pregnant workers.
Domestic rules for holiday time and pay during maternity and paternity leave exceed EU requirements.
Investment in infrastructure.
The EU invests in nothing - it merely returns some of our own cash to us, with conditions and after running it through an inefficient bureacracy. In fact, due to the requirement for match funding and the consequential reduction in our rebate, it is of virtually no use at all.
Emergency health care in other EU countries.
Switzerland participates in the EHIC, so we could too if we wish. The cost to the NHS is far higher than the benefits to British tourists, though, and if you've ever needed to use it you'll appreciate that comprehensive travel insurance is still required as acceptance in practice is patchy at best.
Emergency consulate assistance if there's no UK embassy or consulate.
The UK has one of the largest networks of diplomatic missions, but these have been suffering as trade and commercial matters are handled for us by the EU. These arrangements are commonly set up between non-EU countries too - it is not particular to the European Union.
Safer air travel, thanks to blacklisting dangerous airlines.
We have been certifying airworthiness domestically since the Air Registration Board was established in 1938. It's amazing that people really believe that it is only thanks to the EU that these things now happen. Obviously in a Brexit future we would work with neighbours to ensure safety across our skies.
Better compensation for travel delays.
Ever tried to claim it?
Better consumer protection.
The vast majority of which brings the EU up to standards applied in Britain for decades.
Y'know...just for starters.
Which is true, you can't disagree that is how we became rich and powerful?
