I can see you are unfamiliar with YouTube. The videos you describe sound absolutely pleasant and worthwhile, compared to the actual YouTube content.
Go watch YouTube's biggest star with the largest channel -- PewDiePie. More than 15,000,000 subscribers. Obnoxious, screeching, loud, inane Swede who calls his fans "bros" and the collective the "bro army" and pulls in something like $6,000,000 USD
This looks to be one of his most recent videos: https://www.youtube.com/watch?v=HqpECat4whU
This is his *own* compilation of some of his "funniest" moments: https://www.youtube.com/watch?v=gRyPjRrjS34
Basically, his "thing" is talking like he's mentally retarded, screaming at the top of his lungs for 80% of the video, and using "rape" as a nearly constant element of "comedy" (he even wrote a song called "It's Raping Time" on one of his videos).
Then there is the girl who is a millionaire from doing "makeup tutorials" and the girls who do "my haul" videos that are ridiculously popular and earn a ton of money (these are videos where they go to the mall, do some shopping, come home, and show you what they bought).
Here's another guy who is in the top 10 or 20 of all Youtube "stars" and also earns millions of dollars for it "Smosh": http://youtu.be/yFGBjXqwzbw
Here's another dude who makes something like $5,000,000 -- and all he does is show other people's videos while commenting over them: http://youtu.be/MS8Dbvv5qss
AnnoyingOrange makes millions, too. It's an orange with a talking mouth superimposed over it. It's the most idiotic "humor" ever. It makes Larry The Cable Guy look legitimate: http://youtu.be/EDKjywzRidI
This "Tobuscus" guy makes a couple million dollars and is in the top 10-20: http://youtu.be/omGX5bleG8g
Jenna Marbles is somewhere around #3 and makes around $5,000,000: http://youtu.be/FCichOcSqz0
This Joey Graceffa guy just wanders around blabbering non-stop while recording it and does something like $200k: http://youtu.be/HH74qrfbuP0
