Odd turn of phrase, you used, vetuste. I can concede defeat, during a game or match; I can concede that I've got something wrong. I am unable to concede [contention X] when I have not yet asserted X, nor even its opposite.
So, in plain speech, is it possible the two cultures are incompatible?
I don't like to think that they're incompatible but don't ask me how to go about making them compatible, if they are basically not.
In any event, it is not about the culture clash, it is about sheer competition for survival space, educational opportunities and life chances.
