It's time to face up to it, most people don't see copyright infringement as being all that serious. That includes the big copyright advocates that get caught with infringing material on their websites or who never quite get around to paying the artists their royalties, or who claim copyright on things that expired years ago. Right down to agencies who collect "for" artists who never agreed to their representation and who never see a check for the amount collected.
Meanwhile, it can't be THAT big of a problem. The various media companies make more money every year.
