To where (it's)

[Zipporah Schumaker]

(idiom) an informal expression used to express that something has changed--usually for the worse--or that situation has developed into a particular state of affairs
Cultural context: To where (its) is an effective and efficient communication tool. However, there is a socio-economic divide regarding its usage. The expression is most often employed by [yokels], commonfolk, and blue collar types. It is rarely used by their highly educated white collar counterparts because the phrase is foreign to some and consciously eschewed by others (e.g. the factions of yuppie douchebags who think their [shit dont stink] and [pedantic] stick-up-their-ass intellectuals who cherish proper grammar and strive to speak in paragraph form.)
