I'm not sure why anyone would expect "the average Joe" to maintain some semblance of integrity when very few successful individuals do the same. The overall message is pretty clear - if you want to succeed, you will need to cheat.
Many humans seem to be incredibly short sighted
I want to believe this, but I'm not sure it's always true. Timing of opportunities matters a lot. Someone who is not as skilled in programming probably cheated their way into a FAANG job during the height of the pandemic and made absolute bank, perhaps being able to sock away $200k-$300k since then. That money could then be invested and start compounding, leading to a materially different outcome from someone else who played it by the rules and was better.
The long-term for the cheater might be to simply find a less demanding job and continue riding the prestige hike they got when they snuck into the FAANG job.
Everyone seems to have come out of the pandemic convinced that they need to tighten whatever screws they have to get theirs. And that triggers other people to do the same thing. Cheating enters the realm of possibility because people (correctly and incorrectly) believe others are doing the same thing.
It's gross and feeds on itself. I'm not sure what will help it get better.
