Earlier quoted context omitted.
I feel like you skipped a step here. Why would needing to move to a city and use computers cause "toxic" behavior?
My interpreting of the use of the word “toxic” is that there is an unbridgeable communication and understanding gap between generations when it comes to professional opportunities. In 2009, I had someone in the older generation tell me that success is simple, just have to get a temp job like they did in finance and rent an apartment.
I experienced this myself to a pretty significant degree, and I wouldn't describe my parents' misunderstanding of the modern economy as "toxic" in any way, so my personal data point is not helpful here. Hence my question: what is the mechanism by which this understanding gap is assumed to lead to toxic behavior?
