I think that's a little too optimistic
Rick wants to move towards civilization--better off than the world they left behind. Alpha is the complete antithesis to what Rick is trying to accomplish
As optimistic as that sounds I don't think its completely possible to be better than the world they left behind, you can be at about the same level, but its really difficult to be even better. The more advanced you become, it inevitably brings more problems. As opposed to Alpha and her group, who don't really have to deal with those issues because their way of life is so much simpler.
Rick's way potentially causes much more internal strife, while Alpha's hardly causes any from what we've seen. Alpha's way of doing things might seem dumb and unethical, but overall they have a lot less to deal with Rick that's for sure. Historically less advanced groups/civilizations have also been more egalitarian than those who were more advanced. I think we're gonna see even more of the contrast between these 2 groups in the future.
Rick thinks he's dealing with a bunch of savages, and he's reacting the way Kirkman wants everyone to react. He needs to realize that they're just a product of the environment, they've just adapted in a different way.
Rick's way isn't the only successful way of living in this world. Alpha's has no doubt been successful no matter how barbaric it may seem.
While Alpha may be the complete opposite of what Rick is trying to do, that doesn't mean Rick can't work with her if he recognizes some benefit from that interaction. He really needs to put that aside if he really wants to be better off.
Unless they do something really bad, which in that case, yeah that ain't happening... I don't think they will work together anytime soon, since Alpha has clearly stated that they want to be left alone. I still think it will be some sort of a unsteady truce/agreement, with Carl and Lydia's relationship possibly being a big part of that. But if anyone important on Team Rick gets killed, its on.
