No.
That’s the contribution, not the cost.
To know the cost/profit you need to also know the value of the benefits. Which is hard to determine and would be subject to a range of opinions.
I asked Chat GBT for its opinion. This is what it said:-
“Most independent economic studies concluded that:
- The economic benefits of EU membership (especially via trade and investment) outweighed the direct financial cost.
- The Centre for Economic Performance (LSE) and HM Treasury estimated long-term GDP was higher due to EU membership.
- However, those studies often focused on aggregate national gains, not localised effects.”
