This cult of relativism really needs to stop.
Home that's more clear.
There is a big difference between education/enrichment and entertainment and while some content creators might walk the line between them there is a pretty big split.
I would say pre-defining what is “valuable” is probably not the best approach because it too prone to selection bias, an instruction video on how to do nails to a beautician is far more useful than a video explaining correspondenant banking systems.
That said the content as a whole can be measured in terms of its impact on cognitive and emotional state and well being especially on large sample sizes.
We already know that social media voyeurism causes a lot emotional distress, we know that certain types of content can make you “dumber” at least in the short term.
And on a larger scale we can check the social and individual benefits for specific cases, e.g. how many individuals who watched a specific subeset of content turned their life to the better in say a period of 5 years.
That's also the reason today we have substantial ZERO innovations and capacity to produce new things.
The young will give you a well simulated part/assembly ready for first prototype, the ancient normally gives you small note and a drawing. Prototype the two: the younger one is generally far more complex to being build, costly and far less effective than the ancient one. And it's not a matter of experience, it's a matter of different way of thinking.
Today we spent enormous time in bureaucracy with ridiculous stuff from ITIL/Kanban to the last bit, we spent enormous time in detailed reasoning being on contrary incapable of see the big picture. That's why for instance in shipping company when a (rare) EU doctor (we have less reformed medicine studies than the USA) went in the USA local seafarers they put themselves in the queue for being visited by "real" doctors.
Also, if you travel the world a bit, you'll easy see how most "mean acculturated" countries offer generally a better life quality, life expectancy etc.
Also, when you tell someone "if you travel the world a bit", it makes you seem like a stuck up cunt standing on a soap box that attended too many liberal arts classes and you're just regurgitating what your teachers told you since you don't have a single independent thought or experience of your own. Just sayin'.
I do not say that nail art should not exists, only that reward you get from it should be proportionate to what you give to our society so I expect that a good plumber being rewarded more than a nail artist. Simple as that.
On different countries comparison, I'm living in French, have lived in Italy, Sweden, a bit of stay in USA, UK, CZ and Rus. I compare plus and minus I see in all that countries and that's my conclusions. Never attended a "liberal art class".
Who are you to say nail techs don't contribute to society? Getting my nails done as harm reduction strategy for a mental illness is an enormous boost to my quality of life. I'm often in a lot of pain because of my cuticles or because I've got some picking spot I can't leave alone, and getting my nails done always comes with a sense of relief for me. I've gotten less and milder staph infections since I started getting them done regularly, too.
Don't poo poo on nail techs, man. Most fabulous, glittery "medical treatment" I've ever gotten.
