Aside from Kim Khardashian, are the other Khardashians millionaires?

Well I remember an episode when Bruce, after his wife grounded him from access to money, needed to borrow some money from Khloe, and she just happened to have something like $600 in her wallet and handed it over to him. I know that Khloe and Kourtney own a clothing store called DASH, and I suppose they earn a bit from that. The mom owns a children's clothing boutique. I think for the most part, aren't they all milking the money that the late Robert Khardashian earned from being a lawyer, most notably as defense attorney for OJ Simpson? That's just my presumption.
