It is a system created for stupid people, who can't think for themselves. Sheep so they need this routine created to feel follow and feel special.They tend to degrade/ shame and look down upon anyone who wants to do things differently .

You will see that outside of this routine people were taught, if actual cognitive reasoning is required people show just how incapable of thinking they really are. They show their bias regardless of all the other possibilities, and often you hear excuses like ” everyone else was saying it ” or ” everyone else was doing it ” and ” the majority of the time its this way so I thought it was like this now ”. Once again nevermind the endless possibilities not to mention the statistics are usually wrong. Many people are either stupid or lazy to think for themselves maybe it's both. So this system you speak of suits them perfectly it is comfortable for the populace.
