So long as there are humans who want to amass power in some way and treat it as a zero sum game, there will be other humans forced to play similarly. Prisoners dilemma.
We didn't get here overnight, but economic inequality dominates as a causal factor for nearly any socioeconomic phenomena you can identify in 2026. This is what happens when the top 10% of income earners comprise 50% of consumer spending, and you need to be in the top 15% of income earners to afford permanent housing. If you're a 30% parent (better off than 70% of households), the most important thing you can do for your children is to ensure that they end up in the top 15% or better yet the top 10%. Anything you can do that will help that end, is worth doing, and every moment becomes a competition to set things up as the earlier you do it the bigger the impact in the results.
There's a reason why home prices are correlated to with school district access, why every children's activity becomes a competition, and why in the wealthier (but more rat-racy) parts of the country people spend huge money on private tutoring, education, and training for their children almost from birth.
Not to mention that any large event takes funding. It may not be "for profit" and even if most or all the needed resources are donated there will be people competing for those donations.
"When a measure becomes a target, it ceases to be a good measure"
Parents find kids get ahead by not only good grades but also by winning in science fairs, sports, or disability claims, so they figure out ways to game those systems . . . and, their value as a measure is eliminated.
With few exceptions, these are now only a measure of how well their parents gamed the system.
