Quite a few people have referred back to Vicki's purchasing a car for Brianna when she was in college, and sticking Brianna with the car payments. I clicked on the link provided upthread that linked to Vicki's instagram page, and saw that Briana had replied to some of the posts on there. In one of them, in reply to a poster who called her a spoiled brat, Brianna replies that she is not spoiled, and that she ended up writing a huge check to Vicki to repay her for the some of the cost of the car. I just found that very interesting, and somewhat telling.
Many of the Housewives from across all the franchises turn their hand at starting a business while on the show, or scoring endorsement deals. I know most of them fall by the wayside pretty quickly, but Vicki seems to always associate with low rent partners, and generates zero dollars and zero cents. I mean what hasn't she tried? If I recall correctly there was a jeans/denim line, a jewelry/"diamond" line, the bacon flavored vodka line and the book that probably sold 3 copies.
