It is important to understand the relationship that the psalmist is making.
Society depends on moral foundations.
The psalmist is looking at the fact that whenever the foundations of society are undermined, then what have good and righteous men done to prevent its impending collapse. Some quite correctly quote the Scriptures in saying that Jesus Christ is the Foundation and He cannot be destroyed. In the context in which this verse from Psalms 11 is used, we are talking about the foundational knowledge upon which our moral framework is built. The foundational knowledge of Jesus Christ as Creator can be removed in people's thinking, whether they are from Australia, America, England, or any other society. This action does not mean that Jesus Christ is not Creator, nor does it mean that He has been dethroned.
