That's precisely why the UK got a rebate, because the subsidies were not applicable to the UK economy, which had a disproportionately low input from farming, thus for our financial input we weren't fairly rewarded.
The UK has had a declining car manufacturing industry also, so the same applies to German industry.
The redistribution of contributions may very well appear fair on paper, but countries cannot simply magic up a pivot to farming and automotive industries as a way to receive funds...
