A united fiscal policy would mean a central fiscal union on top of the monetary union - whereby countries in the Euro area would surrender sovereignty to a higher, elected power. This would mean turning Europe into the United States of Europe. A fiscal union would be able to cut government spending, how much each government would be able to borrow, and lend. It would control the economy in a way as to not risk the stability of the Euro for the benefits of one nation. Practically, its socialism on an international level - which is precisely why it’s such an unpopular opinion.
