Subsidiarity to be defined from the bottom up

The real question about subsidiarity is who does the defining. The defining should be from the bottom up, not the top down. The United States is the most successful and enduring example of a large, diverse population within a single federal framework because 'the powers not delegated to the United States by the Constitution, or prohibited by it to the States, are reserved to the States respectively, or to the people.' This fundamental notion that the people are the sovereign is the tenth Amendment to the Constitution, adopted as part of the Bill of Rights four years after the Constitution itself, to restrict the power of the central state created by the Constitution.

The Danish people clawed back their sovereign power when they rejected Maastricht. It was thus the Danish people and not a European or Danish central state that defined clearly who does what.
