The first is its merely a factual observation that there's a social media trend of non-poor people goin it alone pretending to be poor for a very short amount of time and then writing about it, usually online. There seems to be no area for opinion about this factual observation.

Secondly this is example X of the same experiment with basically the same conclusions. It would be WAY more interesting for someone to try an experiment of say, teaming up with someone who knows how to be poor? Agile / pair programming development techniques applied to being poor for a weekend? That would be very interesting. Being poor is a learned skill, to some extent, so its not necessarily insightful that the first couple days of a new skill don't turn out so well. Try any craft, like perhaps metalworking, or any skill, like perhaps a new programming language, or any sport, like perhaps snow shoeing, and your first couple days are probably not going to be very successful and thats not entirely insightful. Its not much of a critique that fifty people have independently released version 1.0, and here is an obvious next step roadmap for version 2.0, someone Please try it?

The third thing which is the only valid critique I raised is the story as presented was hair raising because I live in a cold climate almost all my life and have many cold climate outdoor hobbies and I know plenty of first aid as relates to cold climates, and the subplot of the story was a pretty good autobiographical example of early stage hypothermia, to the point of being creepy to read. Feel cold for awhile, and hungry, then the brain gets really foggy, then unusual ideas start flowing as the body shuts down, then extremely sleepy... I genuinely thought it was going to end with an ambulance. Nothing wrong with an experiment or observation taking, but try not to get hurt? Listing the symptoms of hypothermia in a story format is interesting but distracts from the main story. I think this is a calm, fair, reasoned, and fundamentally useful critique.
