Are the European Commission and Germany the last bastions of conservatism?

Monetary policies (in the United States, the euro zone, Japan and China) are still very expansionary; in many countries (United States, France, Italy, Japan, China, etc.) fiscal policies are also expansionary. The "standard" economic policy is now therefore to have both an expansionary monetary policy and an expansionary fiscal policy. What are the forces of resistance to this trend? The only resistance to expansionary fiscal policies comes from the European Commission (via the European Union's budget rules) and Germany (via the reduction in the public debt ratio). Are these "bastions of conservatism" right? The European Commission and Germany probably think that not only because of population ageing but also due to the risk of resurgent inflation, it is not advisable for public debt ratios to increase. This is a key issue: is it too risky to give up all restrictions on the application of economic policies?
