Your Charles Xavier impersonation needs some work when it comes to mind reading.
I don’t want to see Marvel fail, but as Alex says: capitalism.
The American bookstore market IS Marvel’s market, as is digital; it distributes in all channels.
And since there are 3x as many indie bookstores as direct market LCSs - which also carry manga, by the way, so Marvel is directly competing in that distribution channel as well - not to mention Amazon, not to mention big box stores such as Walmart and Target that carry print graphic novels - it’s a far larger one. If Marvel’s goal, as we keep being told, is to ensure the next generation will read their comics - why aren’t they in the largest distribution channel where they would have the most access to new readers?
Y’know who is in the market? Scholastic, which sells direct to school kids through its book fairs, and who is having great success with licensing Miles Morales (but that counts as a Scholastic book, not a Marvel book).
Pointing to the one smallish channel that Marvel might be successful in (because as Heidi MacDonald among others has pointed out, we don’t have reliable monthly floppy sales data) while ignoring the entirety of Marvel’s market is ignoring how business works.
And if any company knows how to crunch numbers and analyze markets, it’s Disney. Granted, Iger and his lieutenants have much bigger problems on their hands at the moment.
