There two parts to writing in general: the idea, and the skill. The idea is like a rough diamond – the better it is, the bigger the diamond. The skill is then what cuts and polishes that diamond, makes it really shine. If you have the idea but not the skill, it might be enough to gain interest (provided it's really good), but it will be a far cry from what it COULD be if you had skill too. If you have the skill but no ideas (or just generic ones), you might be able to milk what you have for what it's worth, but it will never become a hit.
The sad state of affairs today is that the various publishers, practically everywhere from books to video games to movies, are filled with people who may have the skill (well, that's the good option, really. Most don't have even that and gained the job through nepotism or a flashy CV), but are creatively sterile, which is why you see various shit ideas rehashed over and over and over again. Then you've got the passionate amateurs, usually to be found making fan games, writing fanfiction (in Japan, perhaps trying to write their own light novel), and occassionaly even trying to write something of their own. You can find a lot of creative people with great ideas there, but by and large, they cannot write their way out of a wet paper bag. It physically hurts to read their shit because they don't know how to – learning how to write things is actually really difficult, and various modern concepts really do not help it (in truth, the best textbook on writing I've found was The Elements of Style by William Strunk Jr., written in 1918).
Now we approach the root of the problem – where does someone creative learn how to write (provided he is even motivated to do so)? School? That's how you get blue haired whales with shit in their heads, who then get jobs in the industry (thanks to that degree) and only if they are very lucky. Most people writing for the fun of it made different (and probably a lot better) life choices. You can try to self-teach, but that's dangerous – it is incredibly easy to pick up shitty writing habits that'll just make you write even worse than before. Ideally, you'd find someone who's already experienced in the field and is willing to spend some of his time to mentor you, but it's hard to find someone who actually knows his stuff and is willing to do this. Thus, most of the creative people end up having no skill, thus getting instantly rejected should they even dare ask for a job in the writing field, while the field gets filled by people who may have some writing basics down (and let's not kid ourselves, those basics aren't much either – to really learn this stuff you need experience, ideally writing a book or three), but not a shread of creativity.
The biggest problem I see is that there aren't really proper places for people who write for fun to meet, exchange ideas, and compete with each other, no place where tens of thousand or hundreds of thousands amateur writers enter fierce competitiong, ribbing on each other, criticizing each other and teaching each other, no place where they can display their creations side by side and have the people decide which ones they like the most, and have competitions where the judges pick what they deem the best story. THEN you would have a great pool of writers to pull from – creative and skilled, with experience behind their belts, being offered jobs for their accomplishments rather than for some degree of dubious worth.
No such place exists to my knowledge, however. Those few sites that attempted to create this are either dead empty, or are the domain of a couple hopelessly amateur writers who never get the feedback and guidance they need, for they're surrounded by a small group of ass lickers that will praise whatever they write. The biggest place I know of that had something like this was a site for fucking fan-fiction, but you know, you'll have a hard time finding someone experienced in such places to help you grow, and it usually isn't a place where companies would seek out perspective hires due to its (rightfully earned) infamy.
