I'll be honest from my experience at coaching course's and looking at the academy system in Holland, it's not like there is a 'huge' amount of ethnic minority coaches out there. From my experience on my C license course there was maybe 1-2 Asian participants and a single black student who dropped out after the C license and took it no further (Know him from Sports Science course at College) and he decided to go into the Personal Trainer profession for whatever reason. I honestly don't think the coaching system discriminates against the ethnic demographic, you could argue the cost of the FA ran elite courses prices out alot of the 'inner city' ethnic minority demographic. Another factor is most of the British ethnic footballers in this country are solely focused on playing football (Semi Pro football is full of minority footballers who didn't quite make it professionally). For all the faults of the coaching system I really don't think it can be accused of being racially biased, in my experience it's purely a case of either not enough serious interest in coaching at the highest level or a simple lack of ambition to coach (Many would much rather play semi pro/non league football).
I don't think there can be such an outcry against chairmen to be perfectly honest because the majority of the time I would say that the 'middle class background' coach who's taken all his qualifications/courses will take priority purely based on what qualifications he holds. I remember doing a 2 month internship at a Dutch academy and there was plenty of ethnic footballers in the youth ranks but the only minority member of staff was the physio.
You can argue the same about Sports Journalism and why it's a field dominated by white males generally. I can't explain that one as fully except for the lack of access to SJ courses and possibly the cost of them.
To sum this up, the way I would 'fix' this is to incentivise young ethnic minority coaches at C level/Even from school level of GCSE/B Tech students. The FA needs to find a way of getting young students interested in coaching professionally rather than playing semi professionally.
The 'they're not good enough' argument could only be stood up if they a) Have the basic pro license requirements (I.E Never ran an extra curricular course abroad) or b) They just failed to impress chairmen in their interviews, could be down to presentation/lack of ambition/any factor but I really, really, don't think it's their race that holds them back.
I'm not blaming the minority's but nor am I blaming the chairmen who I saw Darren Lewis so quick to condemn this morning. Some form of grant (I would prefer some form of 'FA loan') offered to some potential coaches from ethnic backgrounds, preferably from SS courses, in my opinion would get alot of ethnic minority coaches involved in professional coaching because at the minute I think there is definitely an imbalance be it the cultural difference's/social class difference's/demographic or geographic difference's. But for people to claim there is this vast supply of unemployed fully qualified ethnic minority coaches out there is wrong as far as I gather from personal experience.
I'm not a fan of this 'quota' idea, I think it creates more problems than it solves.
