>Could you elaborate on this disproportionality?

It's disproportional in that it's more than the swedish would want to give since they'd rather invest it domestically (in energy production and those prices).

>By the same token, we should stop exporting fish and oil – that'd be sure to lower the price of both commodities domestically.

It would and I suspect you might take issue if your consumer prices were relatively higher and you were told you could not build a sovereign wealth fund to the same extent and should instead give much of that money so the eu can build bigger pipelines so germanies prices can remain relatively low.
