I don't think that's quite true. I know Moriah was working at a gym and I think Micah at one point was either working at the gym as well or at a mechanic's (similar to Ethan). I will say that if Micah is able to earn money from modeling, that IS a real job.
I can understand why people feel tired from the 'drama' on the show, but I don't think it's made up. Both Ethan and Olivia have individual and together as a couple gone through major changes in how they see themselves and their values. Especially with Ethan's confrontation with his parents, that made a huge shift in Ethan's viewpoint. It's not surprising, this was probably coming. But it does mean that the way their relationship worked will most likely no longer work. That would mean there is a lot of friction which can lead to a lot of sadness, confusion, and anger to both Ethan and Olivia. Remember that we are also talking about two fairly young people (~23). They've been going through major changes fairly isolated from proper support systems. That's a lot for anyone, but especially two very young adults. It might seem repetitive to us, but it will take some time for them to figure these things out, if they can be figured out.
