Hi Luis! I can't make a great translation into Spanish but I can make it more understandable in English: Here's a somewhat simplified version: "I consider this opinion to be incorrect and not just since the unshakable truths of business and management have asserted themselves in the wake of the first bankruptcies of "New Economy" firms." More simplified: "I consider this opinion to be incorrect and not just since the truths of business and management have become clear during the first bankruptcies of "New Economy" firms." More simplified: "The truths of business and management have become clear. They became clear during the first bankruptcies of "New Economy" firms. I consider this opinion to be incorrect, but not because of the previous two sentences." Hopefully this helps a little!
