The presentation culture

It has been nearly three years since I started my bachelors.
And no matter how much I have been trying to avert the presentation culture which is pervasive in each of my semester, it seems that I am at last accepting it as a necessity to accustom myself to this way of teaching.
But I still have my doubts.

I cannot have the patience nor the tolerance to just let go any piece of information that might be necessary.Nor the ignorance or the co-relating ability , whichever way it might be comprehended , to understand the material in the presentation.
The authors of the books are not crazy to write reams of papers with nothing significant in them , not like in some of the answer scripts which some of my batchmates and even a few of my lecturers urge us to do.

Do presentations save time?
I think if one wants a clearer picture, a book is needed , and a clearer picture is what one should strive for.

I think this very presentation culture is in some way responsible for the economic crisis that the world is seeing these days.
Everything was in the form of the high level presentations, the presentors in no way wanted to present the bad-grade mortage debts.
The high level just talked about the AAA securities which they had been cast into.
The managerial fraternity , which has been groomed on this ' presentation culture' were only interested in the high level presentations, forgetting about what actually constituted the AAA securities.
The presentors were paid hefty sums , so were the ones who were presented the slide-shows , either for them turning a blind eye or else for them accustoming themselves to the presentation culture.

If the presentation culture has such consequences that countries could go bankrupt , that people are stripped off their security,stability and peace of mind , I am sorry but I refuse the presentation culture to pollute me.

A grade lost here or there for my incompetence of finishing off with the course ,well I could manage that.
