There were many initiatives like the EU army that the UK blocked. We're no longer able to block anything any more.
The net contribution didn't account for what we made as a result of frictionless trade, did it? And supporting other countries to develop gives a stable environment so it'sworth the money.
The transatlantic trade deal is puny and why would we prioritise trade with far flung nations over our neighbours?
We need immigrants, a large reason for the NHS being so colossally fucked is that the migrant labour we relied on has dried up.
We could always limit immigration, the freedom of movement was dependent on people finding work, we could have refused residency/benefits etc if they didn't but we chose not to.
The COVID vaccines were delivered while we were still part of the EU system. So the EU did not stop us there.
As the the democracy element - we elected EU reps and then had influence over the whole of the EU. Now they can make rules and we pretty much have to follow them if we want to trade.
Plus the prorogation of parliament, several unelected PMs, undermining rule of law, dodgy referendum funding, parade of liars. And now an unelected Lord Cameron is brought in by an unelected PM. Great. That's really taking back control.
We just blamed so many things on the EU that were our own fault. Now the EU can't be blamed any more, the politicians are saying the ECHR is somehow the thing that holds us back from greatness. It's all populist bullshit.
