Because of the degradation of standards with each passing generation.
Old and proper pronunciation and diction are being shoved to the wayside for more "Modern" conceptualized speech and syntax.

While the English may have invented English, it doesn't mean they are any less susceptible to the ever constant turning wheel of time.

because English is mostly German.

like 'tha's against the laur or ide-er?'

oh my god they can't say 'r'

I don't mind if they said it properly. Something like ad-vert-is-ment vs. adver-tis-ment is debatable, but at least with aluminum they spell it the way they say it. They invented the damn language, they should say it the way it's spelled, and I've never seen an 'r' in law.

Well, not so much in the word as sounding like it.
