Deceptive Advertisements

Advertisements are basically public promotion but does the promotion actually resolve its purpose or is it merely a method to lure consumer into paying more than what he understood in it?

Deception, as it seems, has become a marketing strategy these days as most of the ads focus on highlighting the pros of the product or service and hide the other ugly heads. For instance, the lucrative part of every ad of any mutual fund company will be in the clearest of voices but the mandatory part about the red herring prospectus will always be so rapidly spoken that it would seem to be in some alien language. Similarly, no matter what percentage of sale is being offered at any retail store or garment shop, it will simply have a minute " *conditions apply" sign which will sadden any smiling face that has scooted off for the sale.  
Although our everyday cribbing with such ads has become a part of life now but on questioning our conscience we will find that deceptive advertising initiates from us only. I don’t think any professional will write negative points in his CV; rather most of the points would be bloated. Again, when anyone applies in a matrimonial ad, how many factual grey details does he mention there? Thus, the brutal truth remains that deception starts from within us because when most of us advertise ourselves, we hide things, if not lie; Deceptive ads just incline to a grander scale on commercial front.
