@JohnySid.
I have asked you this question before, as have others. I will ask it again. Is the blog you continually reference your own? Are the essays you continually link to your own work? A Yes or No answer would be helpful.
If it is your own blog, as I and others suspect, there is, to me at least, something faintly distasteful with the way you continually promote it. To me,It smacks of self- aggrandisement and self- promotion, and neither trait builds confidence, or is attractive, come to that.
Worse, you reference this blog as if it is the true font of all that is justified, rational, true and correct, when of course this blog can only be your own opinion, however justified you think that opinion might be.
If someone offers a link to a newspaper, then I can have some indication as to the tone and the bias of that article that is being linked to. Background research on a named author of a piece can also inform one of the likely bias or interest of an author.
A link to wiki or similar at least offers the prospect of an article or reference where some attempt at being impartial is made, and it is often clear in the article itself if the tone is controversial.
We have no such guidance with links to a blog by an anonymous poster, especially one who appears to favour self- promotion.
On to the topic of the OP. Its an interesting point of view, but the central idea - that one single factor, in this case religion - would be the cause of the economic problems that the Euro is facing, does not ring true. I have heard the case made before - that somehow Catholicism breeds profligacy whilst Protestantism breeds thrift, but the justification for it is almost always situational.
