Destruction of the English language.

Everywhere I go, both at work and in my everyday life, I come across this kind of semi-English language. For example, the use of the word "innit", after any statement or question, just drives me up the wall!
"I just had this bill in, innit.."
"Can I help you with that, Sir?"
"Well, basically, yeah...." yada yada yada....launches into full story..

The term "basically" in every case nowadays, is being used to describe the full situation, rather than "in a nutshell" or "to cut a long story short". I believe the word "basically" has been the only four-syllable word that some people were taught at school, it has to be - it is used in almost every situation.
The advent of mobile phones has not helped the situation either, and primary school children regularly use txt-spk when texting each other. I feel these mobiles should be banned for children at an impressionable age who should be learning proper English, and not 'shorthand'. I worry for their future working life and even the ability to write a letter or fill in a form. It is hard enough for them today, with most of them using email with spell-check (used only if they care enough to at least appear to spell correctly) But what about reading? It will be so difficult for them without a standard education. Will publishing companies go bust due to lack of sales in books, in 15-20 years time, or sooner? Young girls (and boys) are more interested in visual imagery, pictures of celebrities, clothes, shoes, cars, computer games, and apparently it is also a perfectly acceptable thing to have "attitude". In my day (which wasn't that long ago!) that just meant "cheek" and we got a clip round the ear for it.

I worry for the state education system now and in the future. We are bringing up semi-illiterates. I recently was asked by a 21-year-old whether the River Clyde was a sea (!!) , to which I could only advise them to look it up on Wikipedia, and if they still weren't sure, then to look up "sea" and "river". This is obviously just a lack of education, and it's not their fault, but the fault of those who happen to be in power in this poor country.
