Why did Britain leave the EU? What are the benefits of leaving the EU?

The main reason is that Britain, like the United States, is always a state exceptionalism, and only wants all kinds of privileges, that is, Britain only wants to get benefits, but does not want to fulfill its obligations and pay anything.

Of course, for better or worse, the instability in Europe caused by Britain's withdrawal from the EU will do more harm than good to all countries in the world, although Britain's withdrawal from the EU will undoubtedly benefit Britain in the short term. Britain can immediately save 8 billion pounds a year to pay for the EU's finances. Supporters of Brexit say that 90% of Britain's economy has nothing to do with EU trade, but it is still bound by EU regulations. Leaving the EU will free many small and medium-sized enterprises in Britain from the shackles of EU regulations, which may increase employment opportunities. In the long run, Britain will lose its membership in the EU, it will be difficult for Britain to rely on the EU to play an important role in European and world affairs, and its international status and influence will be greatly reduced. In terms of trade, Britain and Europe have always been as close as lips and teeth, and half of the trade volume comes from other European countries. If we leave the EU, the trade relationship between Britain and Europe will be affected, and London's position as an international financial center and a safe haven for funds will also be affected. If a large amount of investment is withdrawn from Britain, the economic outlook may deteriorate further. British domestic business leaders, including Branson, the richest man in Britain and chairman of Virgin Group, warned that Britain's attempt to renegotiate its relationship with the European Union may constitute an uncertain future and harm business interests. In addition, without its influence in Brussels, Berlin and Paris, Britain will be even more ignored by Washington and marginalized in many transnational affairs such as environment, security and trade. The United States and other allies want Britain to stay within the EU. Once it leaves the EU, Britain may become an isolated regional country.
