JRR Tolkien's son, Christopher, from what I've read from his commentaries in some of the books (which after his father passed away went through, edited, reworked, and released) seems like he was upholding his father's cause, but once you get into the 3rd and 4th generations, the cause isn't as strong and they were probably brought up as 'rich-kids' to boot. I believe that your assumption is a good one... I just hope if anyone PJ gets the rights and kicks everyones ass with the movie! B)
