Reading through the introduction and the first chapters, I found it very current. The last sentence of the introduction reads (my translation):
Why always bury our heads into the sand, close our eyes, use subterfuges, adopt monetary palliatives instead of taking a dispassionate view to certain truths that are not nice to say but that are inexorably revealed by the mathematical deduction of the laws of economics.
Yes, a very current question indeed.
