I would have you start with "Asch Conformity Experiment" then "Stanford Prison Experiment" and then look into how people become jelious and filled with resentment if they percieve someone having any kind of advantage! It is well known that people with low self esteem and people that are very agressive and competitive are many fold more likely to cheat to win. This sorts would be upset if you gave 4 foot tall child any exception to the rules if they thought it gave that child an advantage!
You see this in the business world in corperate America as you climb the ladder a lot of conditions and personality traits that are not represented much in the general population starts to cluster in different industries and different levels of each industry. To the point that extrem bias in those traits and characteristics emerge. You can profile with high degrees of accuracy what people will do well in various trades or jobs. Psychopathy increases as one rises in management/business and politics. Washington DC for instance has an insane bias to towards most of the nastiest combinations of personality traits that are seen as dark lots of Psychopathic and Sociopathic personality traits and think Dark Triad types!
If you want to see some terrible human behavior right out in plain sight for all to see spend a lot of time at youth sports and such! Look at the child pagents parents or dance and gymnastics parents. Brutal!
If you let those injured old farts like me have anything other's might see as an advantage the more resentment you will see especially if any of the people that get these exceptions happen to win. If you let them have lighter rifles than standard for them or for youth and they happened to win you would see a lot of guys flocking to lighter rifles or pushing for it. For most of F Class muzzle devices where not a thing but today they are as common as can be! If you let them have a more powerful optic because they are legaly blind and they started winning they would all want that. If you let them have a shooting jacket because they have some actual handicap then they would all want shooting jackets. Just like everyone wants to blame their stock trigger for accuracy issues! What ever people see as an advantage they will want even if it is worthless and a nothing burger. If some top shooter insisted that the key to their sucess was coffee enema's you would secretly see 1/2 of the field doing coffee enema's each morning at the hotel before they had to head to the match! Often the more expensive you make a thing the more people will lust after it.
The idea of the cream of the crop rising to the top due to competition might be true if just looking at performance but it also brings out a lot of negative traits in people as well. The combination of time, money, oppertunity cost, stress, desire to win, lots of traveling, any shortage of materials or long gunsmithing lead times does not make for ideal situation to bring out the best in a person. For some it is Zen like and for other's it is a crucible or pressure cooker.
It is just like anything you can not keep those with a lack of virtue, morality, intelligence, mental health issues etc....from competing. A lot of people are fairly empty husks with little depth to them. Take away a belief in god and sprinkle in a need for instant gratification and jumping from one dopamine hit to the next and you get bad behavior. I am sure we all have seen sore loser in sports or competitions growing up as kids. Not only did I see it as a kid but even 10,000X more rasing my 3 sons where all of them where scholars, muscians, and athletes.
The way people drive and shop is a good indicator of what type of people they are. Most people can not drive in a civilized manner and obey the very simple driving rules we have in the USA. The world today is filled more than ever with very selfish, needy, weak minded people that have no standards and think that their should be no standards!
So no I do not think we are too competitive! I think we lack moral stability. I think we lack common social and moral standards. I think we lack religious belief in a higher power that we are accountabil to. I think as a nation we are lacking in strong understanding of who we where, are and should be as a nation and nationality! I think we lack good mentors in most of society today! People are no longer educated in critical thinking and philosphy in large part. History is not well taught today and it has such an idological bias that even when it is taught today it is not taught well! You end up with weak men that are not well formed as human beings mentaly, physicaly, socialy,moraly.
I have many hobbies and passions and you see this every where you look at every level of society and in every walk of life from the mundane even like driving!
I dare anyone that lives in sleepy American fly over country to go into Detroit, Tucson, LA, New York, Chicago and spend more than a week on vaction get out into the heart of these places. They act and drive and shop like animals! That is becoming the standard and that is why you see such bad behavior in all sports today at all levels. We are no longer a high trust society.
