Netflix--Why don't they carry the last season of TV shows? (episodes, money)

[no kudzu]

At least twice I have invested time in watching popular TV shows on Netflix only to get to the end and realize they don't have the last season available.
30 Rock I can half way understand because it only recently went off the air but Monarch of the Glen wrapped up in 2005 I believe but Netflix stops at the end of Season 6. I can't find Season 7 free online anywhere. Any suggestions where Season 7 is? I really got involved in 54 episodes and want to see the last season.
Thank you.

I was upset about Sons of Anarchy, but I understand the decision is not Netflix's. It's the show itself that licenses it (the network or producers). More then likely it's a business decision - they can make more money by selling the DVDs, or offereing it as some sort of pay per view. Once they milk the profits dry from those two sources, then they usually sell it to Netflix or offer it for free streaming on other websites.

That.

They have to make their dvd money first before just letting the public eat it up.
