you're making far, far (far!) too many assumptions based on the very, very (very!) little we've seen of earth 2
claire - ended up keeping her son and seems glad she did
all we've seen is her in the hospital having early contractions. we don't know if she has the kid or keeps the kid or if she's happy about it.
locke - wheel-chaired but accepts it, has a job he likes and a MILFy fiance/wife
accepts it, but doesn't like it. was fired from his main job. has only had one day in his other job, which is as a substitute, so who knows if he'll stay or enjoy it ... or if alt-ben tries to kill him.
jack - not a drunk, has started getting past his dead dad and is working it out with his son.
he still hasn't found his dad, has mysterious "i dont remember this" surgery scars, is divorced, and has a patchy, at best, relationship with his son, that he only sees 2 days a month, and whom he just learned enjoys the piano.
sayid - love of his life still alive, has a family and a job that doesn't involve killing people for Ben Linus.
love of his life... with someone else. despite the fact that they both love each other. that doesn't sound too great. plus, he knows he can't be with her because he knows he's a bad guy, i.e.; hasn't made peace with himself, as he had on the island.
...he also just murdered three people.
