hmm. seems like there is a lot of "american bashing" going on insofar as martial arts.
I'm Australian, and I was looking at it from an Australian perspective (aside from calling it a "McDojo" which obviously references an American institution).
I think its the same everywhere. Unfortunately, historically martial artists were "full timers". Whether you were some monk or one of the guys in that crass "kung fu monks" travelling circus, martial arts were something you did 24x7. Its no different to being any other kind of professional athlete.
And like other sports, for every "pro" you get you've got a bunch of amateur people giving it a go to varying levels of discipline. To use motorsport as the analogy (since we are on a car forum) not everyone is a F1 racer but if you go to a pro driving instructor with the aim of being one they'll expect you to do the physical and dexterity training
all the time.
Then there's guys who realise that people do it as a "weekend racer". They're a cut above your average schmuck behind the wheel and get the theory behind good driving but they're not dedicating their lives to it. Pro driving instructors will be a bit harsh on these guys, have a go at them for sloppy lines, but won't expect them to be able to balance on a pogo stick while catching tennis balls.
Then there's the guys getting into it for a lark. Driving instructors who need the money will just rent out a circuit or skidpan and let these fools go nuts. They don't expect them to clip every apex like their car is on rails or carry perfect drifts around cones. They just need the money, and cars is what they do. And they won't tell them that they're unco-ordinated monkeys since these guys won't come back.
Unfortunately its this last set that gets most of the publicity, and so attract the most amount of "capitalists". Guys who will blow a couple of grand massive rims for their Civic but then won't spend a couple of extra bucks buying good tyres. They're the reason why I can find 225 width tyres in 20" (no OEM or anyone with a motorsport engineering background would ever design a car with so much unsprung weight / rotational inertia without a massive footprint to go with it), but its near impossible for me to find a set of 275/45 R17 tyres for my car.
And its why its so much easier to find martial arts schools out there trying to make a buck doing glorified aerobics (they may as well be doing tae bo) instead of teaching people a proper art.
