I understand the feeling, but language is what language does. It will change and you will notice those changes if you're alive long enough :)
Even prescriptivist languages (as my own native language tends to be) cannot escape. I'm bad at my own native language because I've been living elsewhere for very long... but not as bad as the Kids These Days :)
There is no such thing as a “prescriptive language”. What would that mean?
No living language is only used according to the rules laid down by grammar teachers. The only languages that are are dead languages like Latin with zero native speakers.
I think you'll find I used a slightly different word.
