To be honest, Avatar: The Last Airbender has just as minimal frames as many animations today and it's quality is similar, if not the same, with the animes you are deeming "crap".

Also, voice actor quality is not something you can tell since when most people say " The voice actor was CRAP!" is because it is in comparison with the japanese voice actors. You are being introduced to the characters with their original voices, your brain affiliates the character to said personality/voice whatever. Like say...one example of Naruto's "Believe It" phrase.

Many of us cringe at the words. But you know why? You actually understand the words coming out of his mouth. In japanese, a good half of us have no idea what he's saying, relying soley on tone of voice to interpret his "subbed" words. But what did Naruto say to have the "Believe IT!" phrase there so many times? Dattebayo, a phrase spammed practically after every breath, sometimes more than once on the same sentence. He says it so many times, Believe it suddenly doesn't seem that much of a bother. What's worse? Dattebayo doesn't even mean anything! It means even less than adding the word "yo" at the end of every sentence....yo.

Anyway...enough with voice actors. To the "high quality" animation you demand like it's a right. Let's not even assume the half hour of animation (it's not half an hour anyhow, don't forget the ads) Lets just assume...20 minutes. Now lets use the standard FPS for everyday animation, 12 FPS. Now, 12FPS x 60 seconds = 720 frames per minute. Now, 720 frames x 20 min = 14,400 frames an episode. They have to get 14,400 frames done in a week and lets not include the coloring and scene planning and lets not even think about the silly sound effects that add that punch to every frame. And then lets not even think about voice actors.

Now, how many editors? For Bleach, we count a whopping 1, oh excuse me, lets include the incredible 2 video editors. Some members of said crew have multiple jobs. Gee wiz, just why is that? And I always considered Bleach the better among the likes of popular anime.
