Ummmm... no?
What do laners do, during the first 15 minutes of a game, they take objectives? No, they farm and they get items, and maaaaybe they try to take a kill, but the higher you go in ELOs, the less kill there is in lane.
Well, instead of being insulting and demeaning, just realize it's the same for the Jungler. His top priority in early game is getting gold and items, just like everyone else, and you can do that by farming the jungle just as well as with ganks. Of course, a good jungler will recognize gank opportunities and will come and collect the free gold, but no jungler has any obligation to gank, and most of all, no jungler has the responsibility to save your lane for you if you lost it alone by yourself... He'll try to do it if he can, because he still wants to win the game, but it's not his responsibility, and if you flame him for that, well, that's just stupid...
