Why are most manga serialized slop written week to week instead of already completed stories?

There are three factors.

1: The author, whether he or she wants to or not, will have to comply with the whims of his or her own publisher just to make money, not giving importance to writing or other things.

2: This is obvious: your manga will be of better quality if you have more time, but if your delivery time is weekly, that will make you rush, and unfortunately, many times the story is created on the fly without having anything done or planned beforehand.
3: Their own authors.

God why are question threads so braindead

2. isn't quite right
many mangaka need that pressure of a deadline to work properly. Not only in pushing out the necessary quantity to keep a series going, but also to make the author not become too lazy.
The best manga, anime and videogames were produced when people were whipped like slaves to produce content as quickly as possible

There's next to no manga that's published weekly.

You clearly don't mean oneshots, so in your fantasy world you think authors should be releasing 10 volume completed works out of nowhere? And publishers are just handing them money for rent and assistants as an investment? And of course these are expected to sell with no established readerbase.

I mean a manga artist is free to make a complete manga at any pace they choose, including only releasing a complete story. A manga artist taking money from a publisher is not free. The publisher is giving money with the goal of making a net gain of money.

Because every wannabe mangaka is fighting to get serialized in a magazine, and 99% of attempts are rejected. You cannot prepare an entire 10 volume story with characters and all, just to be rejected.
They do 1-3 chapters, or just a one shot for the application. And they might have to revise that for months and keep trying again and again, or drop it completely.

>as quickly as possible
is very different from "on a deadline", and a weekly pace is really not something most stories can manage
also ongoing projects don't have the benefit of hindsight and editing, so it's way easier to write yourself into a corner and/or retcon earlier stuff

a more relevant addendum would be that weekly comics for little boys are designed to go on forever, ensuring the author gets stable employment in a terribly volatile entertainment industry
and everybody wants to eat

why all you kids make such stupid threads asking such stupid questions?
the tourismo generation. kill your selves.

Probably cos it takes a long time to draw thousands and thousands of drawings and authors gotta eat in the meanwhile.
Just a guess though.

Also most manga are not weekly.
