Here is an opposite question, how do ardent remainers think they can reform it from the inside.
It's often overlooked when it becomes people wanting answers from leavers, its so onesided.
I'm a remainer for what its worth, so if some of the more ardent self proclaimed specialist could offer answers to the following that I have gained from reading into the situation, (that so many on these types of threads are fully understanding of)
So lets turn this around and see how knowledgeable you all are and defuse these arguments as a pro eu stance considering most of the replies are regurgitated Guardian headlines, so:
The UK has been sliding into a condition in which democracy has been largely abandoned, or hollowed-out. Engagement with our duties as democratic citizens has gradually fallen away, replaced by a sort of consumerised dependency on the elite to offer us a reasonable range of brands - to give the middle class an acceptable illusion of choice. But it's fooling fewer and fewer people
At the same time, the EU has been evolving into a crutch that politically exhausted elites like ours can lean on, collectively propping up regimes that have minimal legitimacy, domestically. Democratic accountability is specifically and deliberately excluded from the institutions of the EU, with a "parliament" that's effectively a pet focus group the executive can use to check what they can get away with. The entire structure and cadre of bureaucrats and leaders in the EU are entirely clear that The Project ends in unification. But this must not be stated overtly to electorates who value their own democratic heritage.
in parallel to those political developments, Europe and Western Capitalism in general is coming under extreme pressure, economically and geo-strategically, and the measures it took in the credit crunch have only delayed the consequences. The way that the Euro survived, at the extreme expense of southern Europe, ensures that the EU will not continue to cohere when the pressure intensifies - the fault lines are clear.
in this context, the UK elite posed a phoney question to the electorate to isolate some euroscepticism they assumed was just some rogue individuals in the elite. They failed to anticipate how the electorate itself might respond to this opportunity to change the script. When we said "change" they were shocked and discombobulated.
changing is beneficial because (a) it restores the electorate to a position of responsibility in UK politics (b) it removes us from an institution that wants to be a government without a demos and (c) it puts us into the kind of special measures we desperately need if we're not to walk into the next crisis flabby and dependent on those stronger than us to tell us how it needs to go.
So what is the counter..
