Except they didn't follow my advice because I or someone else thought it would be cool, it bedmates of the market. People just weren't buying enough comics do they had to target a niche more and more. You say there is some kind of hidden audience that would buy comics if they just stopped portraying female characters the same way they portrayed spiderman? In sure there are some people that feel that way, but I don't there would be enough of those to support the industry, because, again, the internet and other mediums are just wrecking their business.
Also, what other countries really have a healthier comic industry than the US of you exclude manga and manhwa? Not to mention that a huge portion of manga actually is the same as US comics. There are just a bunch of others as well. Not to mention that in Japan you have to tie in the merchandise, light novel, and anime industries to manga as well. There are no popular equivalents for some of those in the US.
