Lots. I mean.. LOTS. Here's a sample: * Better regulations. Yes, this can be handled locally, but at a large cost. * Lower prices of goods – the EU ‘Single Market’ for all member countries is a massive saving. Impossible outside of the EU. * Free movement. Citizens are free to move from one member country to another. This is actually a massive boon to both leisure and commerce. Impossible without the EU. * Creation of jobs - over 3.5 million jobs in the UK have been generated over the years. Not massive but the economic hit would be painful outside of the EU. * The Structural and Investment Funds. Places all over the UK (and the EU) have been redeveloped, had economic investments, and companies funded. This is just not scalable economically outside of the EU. * Louder voice – Britain isn't an Empire any more. It might be the 2nd largest economy in the EU (9th in the world) but without all the others it is a much smaller voice when it comes to agreements - plus it would have to negotiate agreements itself again. This is a surprisingly subtle one in terms of impact long term. * Workers protections – the European Working Time Directive for a start but lots of other protections for EU citizens exist. There are more, but this is a good example. Turns out btw that while EU membership costs the UK a bunch per person it actually more than makes up for it once you factor in a lot of the costs it has saved us as well.
