I wish I could make some sense of this. I think I understand how the payment is calculated, but have no idea where they derive the benefit received back from. Even in the extreme case a portion of agricultural subsidy, must in some way translate into lower food prices, would you agree ?
The benefit back is direct subsides of things like new roads. I'll agree that indirect benefits such as tourism because a visa isn't required aren't accounted for. As for us receiving anything for the CAP - a very large majority goes to France and then less so to Spain and Italy.
