Now, a lot of people will say, "Well, people today are different! Back in the past, we never saw this uncivilized behavior!" Oh, but we did. We just didn't see it as much as we do today because the people who did this - unsophisticated, uneducated, poor, trashy rednecks and the like - were not as prevalent as they are today.
NOTE: This desire among the lower classes to "win" at things that are meaningless, or to have their children "win" at all costs extends to other areas of course. The Little-League Dad who beats up an umpire or shouts obscenities at the young players, for example (or pick the sport, there is likely to be such a "Dad"). Parents who finish their children's homework or science projects "so they'll get a good grade" - but fail to learn anything of value. Parents who spend hundreds if not thousands of dollars on Halloween costumes for their kids, or pay for hotel rooms on Prom night.
I think the common denominator is parents who are trying to re-live their (failed) lives through their children. I was lucky in that for the most part, my parents didn't care all that much, which in retrospect, made me more self-reliant. Maybe that is why the millenials seem so helpless as kittens - they have had everything done for them up to this point in life.
NOTE: Some folks, if you try to discuss this issue, accuse you of being racist or "elitist". But poor behavior (in every sense of the word) isn't based on race, but more on social conditioning, I believe. Look at every race on the planet - each has a share of geniuses and each a share of idiots. Some more than others, but perhaps because of social conditions and not because of inherent racial makeup.
Now look at the people who are racists. White supremacists (and black supremacists, and whatever) are some of the dumbest examples of their respective races.
Racism also negates personal choice which I think is far more powerful than your genetic background. Indeed, some of the dumbest people in the world are the most successful.
I think that is why Liberals are irked by the likes of Donald Trump. The guy is no brain trust, to be sure, but he has achieved a modicum of success (or the appearance of it) in spite of his mental handicaps. And this drives well-educated Liberals insane. "How can that guy make money when I have three college degrees and am still struggling?" - the answer can be found right inside that sentence.
I think what drives this need to "win" at Halloween or Easter Egg hunts is some sort of need to overcompensate. It is a cultural value, not a racial one. And kids brought up in this type of culture tend to follow its normative cues.
Unless, that is, they make other choices. And some do, thankfully.
So maybe there is hope.
