That's clearly not what it's trying to do right now. For one the UK is still a member state and still paying its dues, but the EU is acting in an extremely hostile way. Unless you reflexively define the best interests of the EU Commission and related institutions as "the best interests of all and every single member state", it is certainly not the case.

Consider: The EU is setting things up such that in just over a year trucks will start to pile up at ports, costs will rise across Europe and the UK, many European firms will be cut off from the financing they receive from London, airplanes will be grounded, Irish politics will destabilise due to the introduction of a hard border and that's really just the beginning. None of this is in the interests of any person in any EU member state at all. And it can all be easily avoided.

Your spa analogy is very badly off by the way. Trade isn't something countries sell like a product itself, despite the EU's attempts to package it that way. Countries that strike free trade deals do not "buy" them, they negotiate and agree to them. Think about neighbours cooperating more than a consumer buying a product.

If you go read press releases made about trade deals they always have apparently huge numbers but spread over a very large number of years. Modulo what's said elsewhere about the uselessness of economic predictions, the predicted impact is usually very low. Probably because tariffs are already quite low and falling globally, most trade barriers are now regulatory in nature and those tend to be relatively unaffected by trade deals.

I think it takes a certain amount of bravery to accept that there are no "experts" when it comes to predicting the future.

There simply aren't any economic projections of a trustworthy nature right now.

As just a single example the housebuilding industry has been consistently able to build fewer houses than there are people arriving by a large number, and the statistics over how many people are arriving are themselves deeply suspect - they don't correlate with any other population related statistics, and are based on airport surveys that ask a subset of people whether they plan to stay for a long period.

If politicians allow immigration at levels significantly above the speed at which infrastructure can be built out to support the new people then infrastructure reliability and availability will decline. It is reasonable to be concerned about that if you rely on that infrastructure.

The idea of Brexit voters as incorrigible racists isn't supportable, no datasets of any integrity show that and the brief spike of "omg britain is so racist" died down very quickly after the referendum, simply because the UK is and remains by far the most racially diverse nation in Europe.
