what's happening to the language ?, I can't keep up. Options

Little back ground : I've been in US for ~ 5 years and a couple months, when I came here I knew 0 English, so all this time I've been learning, improving little by little and now I can order a complete meal at McDonald's with no problem lol.
me and my brother collect Jordan Sneakers and we think is time to part with some of them as the market price is reasonable and we need more space to store some more. on our search online for price quotes and such, I have stumble across this web page, and honestly some of the stuff I just kind of figure out my logic, some other I just completely ignore.

Take a look !

we have a similar issue in Spanish and I'm sure it happens to most languages over the net, but is just sad.

one of my personal sayings is "unfortunately, many of us rate human intelligence by the ability to properly speak the language native to a country" because language is one of the first things a person learns growing up. without that first piece of the puzzle, communication is limited. of course, mastery is not expected but the more fluent you become, the more successful you appear (and vice versa).

ebonics and other types of slang talk is unprofessional to me because it shows incompetence to learn basic proper english, and speaking it just to shortcut words (which i think is completely unneccessary because english is pretty easy[try mandarin if you want a challenge]) simply shows that a person is lazy (which unsurprisingly proves to be true) , although i do use ghetto talk from time to time amongst friends (whom clearly know im just playing around), i try to speak clearly and in complete sentences when it comes to my job and/or conversations with others.
