If one defines corruption broadly to include acts by public officials to be taken for purposes other than in the public interest (e.g., for political or personal purposes) and to include acts by private individuals and companies that corrupt public officials for the private gain of those individuals and companies, we see currently an extremely high level of corruption throughout our society. This corruption threatens our democracy, our society and all manner of things we are concerned with, including our education system. What you describe in the textbook field is an example of the corruption of the part of the education system where the power and influence of monied publishers dominates the selection process; these are acts not in the public interest, but in the interest of publishers' profits. Sadly, the media is generally supportive of the powerful, rich, Establishment interests which control the decision making. It is not at all clear whether the level of corruption at present is simply a cyclical phenomenon or a more worrisome indication of an ultimate decline from a peak in the American experiment.
