who pays more, marvel ? starters get a 100 or 150 bucks a page i think, at best, thats not a lot ,well it depends where you live, where i live thats a joke, youre much better off in advertisment, (150 in one hour) but live here is very expensive (one cheeseburger and a coke 7 bucks fifty, at mc donalds). it also depends on how many artists are available for the industry, if your country doesent have a comicbook industry, theres probably not so many good artists, so you can make a fortune in advertisment. in japan , theres probably thousands of good drawers...but comics are also very popular...
i would think you get better pay in japan...
wages in the states are pretty messed up from what i have heard, one comicbook publisher said in a you tube video, he gets offers for pencilling, inking and colloring a book for 2500 dollars a month!!! crazy!!! the artist even using his own computers!!!
i dont know what comics the japanese read, japan is very americanized i think, i once read a book on meditation , the writer said that a lot of japanese dont even know the jap. sign for zen anymore.
