One problem I see is connected to the Left's interpretation of the idea that we are all equal. Equality is about playing by the same set of rules. However, since people are different, one set of rules will not always giveth the same results. The Left seems to think that equality is not about one set of rules, but equal results. This required dual standards; more than one set of rules, to get the same results, such as Affirmative action; discriminate against one to put them in a hole and then to give another an advantage, so we can get equal results.
The problem with this approach is it is harder to make the dumb smarter, than it is to make the smart dumber, so we can achieve equal results. Based on this one irrational premise of the Left, one would expect a net dumb down in education, based on it being easier to get equal results that way. Even smart people will under achieve.
In sports, there are one set of rules for all players, in any sport, at at level. There will always be the top dogs, underdogs and the rest in the middle. Say we applied Liberalism to sports to achieve the same results across the board. Again, it will be easier to dumb down the best players with extra rules, than to train the bottom players to score 50 points every other game. Sports would dumb down to a lower state, because the premise is irrational and designed for failure; victim culture to grow Big Government.
We need to go back to common sense and one set of rules for all. This allows the cream to rise, rather than be held back to satisfy an illusion. The elephant in the room, can be seen in sports. Black males are really good at many mens sports. That tell us, that race and even sex may play a role in terms of personal ability in various aspects of culture. It may not be a coincidence that so many Asians are in higher Education near the top of their classes. The dumb down approach wants to hide this.
In my opinion, this elephant in the room is partially due to genetics but is also caused by the long term affect of cultural training. Black culture is more tribal, which is more celebration; music and dance, and physical competition between tribes. Asian Culture is more about conformity to old rules and the ethic of hard work.
American Culture used to be a melting pot, so children could learn from all cultures, until the Left convince the ingredients to leave the pot. This was reflected in education with everything taught in 10 languages, instead of the one language. From a practical POV, learning English will provide the most opportunities in the USA. Specialty language can restrict one to a single city. This will limit opportunity.
Instead of learning the benefits of the common culture, which represents the best of all, there was a push back to cultural specialization, where not all cultures are good at everything. Again you fix that with the melting pot, so people can become well rounded and not pigeon holed. If you came from a third world culture, and was connived by the Left to celebrate this, one may not be able to fully leave the third world, even in a first world. This is good for Big Government since it creates problems to justify itself.
