This arrangement could lay the groundwork for common EU policies in areas of collective interest which are underpinned by direct EU spending. Against this background, I would welcome a serious discussion about EU public goods so as to identify where the case for them is strongest and how they may be in part financed through the EU budget.
This is precisely what the principle of subsidiarity prescribes: policy measures should be taken at the most local levels of governance unless they can be implemented more efficiently at a more central level.
