Talking to clarify and to inform; not just to make noise
First, these questions are typically the kind of issues which should be discussed within a Eurozone Economic Governance body, as proposed five years ago by Newropeans*, not when a crisis erupts, but rather on a regular basis; not in a non-Eurozone newspaper, but rather within specific Eurozone institutions. Not in a national parliament but rather at a European summit. Otherwise these declarations are just making the debate more obscure and therefore immediately becoming tools in the hands of speculators.
