9/10 its MONEY
people get to certain level in wck and want to teach to earn MONEY, or are often ENCOURAGED to do so...
if they get in a cage and get bashed they will forever be known as 'the guy that got beat' in the kind of circles that most wck associates itself with.
of course MMA is a test and of course wck classes contain very few actual fighters, in the western world boxing is the sport that all the ruff-n-ready kids get into. less so into muay thai and obviously BJJ is growing steadily amongst this ilk.
no one argues that boxers can fight on the street - its almost a given, but that is MORE down to their attitude PRE boxing
a very good friend of mine is the Southern Counties and Northern Counties champion at this present time, and has held the English ABA (2nd class?) title too. a d@mn good little boxer, but cannot, and does not claim to be able to, streetfight.
its just not his nature. although there are lesser boxers at his own gym who would tear him a new @rsehole in a real fight.
they are the ones that have that inbuilt aggression.
if you find a genuinly good wck school you will see that not many 'graduate' to other arts from there. however, you will find that they have 'converted' many other people from other martial arts.
its all dependant on the student and the teacher.
on a side not, my tacher says that wck is not so much about fists, he says putting gloves on limits our arsenal by at least 50%
