What would become if the 5-8 wage slave would realize that this is going to be their entire life? What would happen if a family man realizes that his offspring is no different than his neighbour's? What if a religious person realizes that he has been taught about a specific version of a supreme being because they were born in a particular culture and not another?
Most of the time, nothing spectacular. All of those things happen all the time.
We are so bad at judging reality and risk, that most of us remain hopeful even when we are faced with those realizations and keep finding silver linkings and keep imagining things getting better somehow.
Our risk assessment is so bad that lotteries and casinos keep making billions.
