So much this, people today have no bullshit detectors. Everyone that describes her as a cutie, pretty, a 10/10 etc can't see she's average at best, her body is meh and she has no boobs but damn did those filters do the job.
Also, what a thing to aspire to: Van Life Vlogger. Many here have mentioned that the ones that are successful are trust fund kids raining money on outfitting a van and even they will admit it's a shit way to live. These two didn't have any money and the van itself was crap so the inevitable outcome shouldn't come as a surprise.
This incident is the product of a superficial society, where appearance is everything and insincerity the key to success. People their age used to aspire to getting a good job, marrying the right person, buying a nice home and raising a family, in that order (and up until the 90s most people still did). That's becoming harder and harder to do, nigh impossible for many. I think that knowledge is always in the background, this nagging feeling that things should be different, but they can't quite understand why or who's to blame. So they see a Vice or puff piece on some rich kid riding around the country in a van and impulsively decide that's for them. When it's not at all what they believed the disappointment, depression even, sets in. Not being stable to begin with they take it out on each other. And this clusterfuck is the result.
