American English Dillema

I have to make clear that this clever analysis is not applicable to the whole English Language spectrum, it is limited to the one spoken in the United States. The English spoken in the UK may have other issues, but certainly, the general population has a lot more vocabulary than the people in the US. There is a similar phenomenon happening between the Spanish language spoken in Mexico, when compared to the one spoken in Spain. Fucking crutches only dum down any language. When someone uses the sentence "¿You know?" a lot, its a clear sign that he / she doesn't know a thing, as he / she cannot explain it properly. Thanx Mr. Ronnie Bruce.
