That was meant ironically. The article explains in great length that this quantitative "productivity" does not result in qualitative "productivity".
The fundamental problem, in my view, is that any significant reform of EU procedures would mean strengthening the European Parliament. In other words, EU governments must be persuaded to relinquish some of their sovereignty. Since the signing of the Lisbon Treaty in 2007, there has been no significant progress in this regard. This is also related to the fact that, unlike 20 years ago, many center-right governments are now in power in many EU countries, and strengthening the EU is not on the agenda of most of them—often quite the opposite. France is an exception, but Emmanuel Macron's initiative was met with little response.
For good reason. The United States of Europe is a pipe dream. Why not go in the opposite direction and drastically cut down the entire thing?
> sovereignty
I truly hate how this buzzword is misused with regards to the EU. Voluntarily delegating authority is not the same as losing sovereignty. If you can un-delegate the authority at your own prerogative, you have not lost sovereignty. If the UK, for example, had genuinely lost its sovereignty, it would not have been able to voluntarily withdraw from its participation in the EU.
