It can be argued that the concept of intellectual property is perceived differently by young people today.
In her book Blogs and Tweets, Texting and Friending: Social Media and Online Professionalism, Sandra M. DeJong suggests that digital natives have a fundamentally different idea about what intellectual property is. (You can see her book here)
An interesting example is when a student was confronted about plagiarizing from Wikipedia, he argued that things on the site are considered "common knowledge" in this day and age since the information is so easily accessed by all.
I think that there is also an overall sense from digital natives that what is available online is free for all. If it is posted online, they believe, the author is ok with you using it. Many professionals have said that they are hesitant to put their work online for fear of plagiarism.
Also, I think that students don't see "stealing" online information is the same as stealing "hard copies" of work. For example, a student wouldn't think about stealing a book from the library or a store, but they are ok with downloading music or a book from a pirate website such as Pirate Bay.
