A lot of these videos seem to be about buying stuff.
I hope she finds other, non-costly, things to make videos on.
I suggested that she could make videos on subjects that were submitted to her(like philosophy, politics, interests, etc.). Maybe 1 to 3 subjects per video.
Maybe she can even start streaming on Twitch. Since Youtube doesn't want to add easy to use financial features(paid subscriptions, cheers, etc.) like Twitch, it would be best for her to start streaming on there. It's a great source of income, income that could be used for her more costly vlogs.
A lot of people make so much money, even with a small viewer base, that they can work full-time as streamers. So it would be a great financial boost for her, and it would be entertaining for others to see a person, with a different perspective than those that usually stream on Twitch, playing games(doesn't have to be full-price AAA games. There are a lot of entertaining, and free, indie games). And she would also be able grow her viewer base, since people like to watch the streams with plenty of viewers.
