decline of english

whilst anecdotal factors cannot be discounted: lack of grammar teaching in school, rise of the internet, sms speak, etc, it seems from a pragmatist viewpoint that language proficiency has simply devolved to the lowest common denominator in terms of usage. in other words, good english isn't acquired or used because good english is not necessary in this society - it is neither needed to communicate with anybody in this country, nor needed to understand the majority of things to be read or watched or viewed, nor even needed for the majority of occupations. it remains to be acquired for its own sake, which is why it has attained perjorative connotations in some circles, and used as a discrimator of status or class in others - a kentang outcast or a linguistic tai-tai. both zeroes on the desirability scale. any wonder then?
