I agree with you on this, Lukraak_Sisser.
However, (in my opinion), if the EU finally understood it should be less greedy with the UK, then I think the current long-running crisis in EU-UK relations could perhaps be solved in a very satisfactory way, see
https://fullfact.org/europe/our-eu-membership-fee-55-million/ (already posted).
If, in the EU, rich countries appear as losers and poor counties appear as winners, then the EU will be a magnet to all poor countries while the rich ones will perhaps flee away (including Germany, once it feels it has corrected its image problem). Perhaps, on this forum, you could use your "people's power" to defend such a viewpoint, but this is far from being the case, as far as I can judge.
The point is: if countries were people, they should all have a smile on their face, without some contries feeling they are being taken advantage of, and European leaders should ensure that.
