I just finished reading this entire thread, all five pages worth! All that really needs to be said has been said, and then some. But I will throw my hat into the ring anyway.
I'll stick to the subject of of McDojangs, as nearly everything else has been well and duly covered. I truly feel that the majority of these places do not exist for the sole purpose of fleecing the uninformed. I do think that, at least in the US, the buying public has greatly shaped our teaching methods and business practices.
A school needs money to stay open. If the owner is independently wealthy and can do so without charging any fee, bravo, but that is rarely the case. Also, the majorty of people who take up a martial art typically quit on the way to or just after receiving their black belt. Because of this, schools will go down the path of clever marketing, karate camp, and birthday parties, as well as eight year old blackbelts in order to stay in business.
Note: I am aware that there are slick people who use martial arts as nothing more than a cash cow and set out from the very beginning to do so. These are not the schools of which I speak, and of which I feel are the minority, even amongst McDojangs.
Students and students' parents will potentially sue for just about anything, from physical injury to denial of a blackbelt. This climate tends to encourage a more tepid school than the owner may wish to have. And forgetting lawsuits, the student can simply quit and go elsewhere. Most people in this country have developed an entitlement mentality, so the idea that a martial art does not reward all equally, regardless of effort rubs many the wrong way, though they'd never admit it. People want money that they didn't earn, jobs for which they are unfit, and to be exempt from any penalties, regardless of how grevous their wrongs.
I believe that the continuing increase in the cost of tests as the student progresses also prevents schools from withholding a black belt (or any belt) from a student who does not test well. Admittedly, a student shouldn't be allowed to test if they aren't ready, but that is another subject.
Personally, I see nothing wrong with the whole birthday party thing; if the actual class is a decent class with quality instruction, then I really don't care if the owner uses birthday parties or karate camp to supplement the school's income. I
do have a problem with eight year olds being permited to wear anything more than a poom belt.
My last comment is this: You get out what you put in, regardless of where you train. If a student trains hard and with dedication at a McDojang, they will inevitably get more out of the class than those who mail it in. In fact, I'd venture that a lot of instructors at McDojang schools are very happy to have such students when they come along and take the time to cultivate them.
Just a few less than organized thoughts on the subject.
