Ok so, for a first story, it's fairly good. You however, need an editor/proofreader badly. There's a fair number of groupd as far as I know that you can check on that should be able to help you out. For now though, I'd suggest running this through a spellcheck and grammer check if you can.

(Please note that I have no intentions of being rude and that I want to offer constructive criticism)

"Alex fumbled with the sleeve of his hoodie before he spoke carefully. "I-i know Miss Fig, and i am terribly sorry, but my boss the fat fuck wont give me my pay for the last two months, making me basically bankrupt."

Correct me if I'm wrong but I'm pretty sure its 100%
Illegal to withhold payment for that long

"With a sigh and a shake of his head he then made his way to his work, wich he hoped would take his mind of things. He worked at a place that stored foods and other goods that would not be digestible for very long if not stored correctly.He was alone most of his time there, packing things into shelves and the so called cold room"

I feel like the parts where you included Alex's job could be described in better detail

"Big sis, can ah go with the others and try to get our cutie marks in monster huntin'?"

"Why of course ya can, jus' make sure you stay out of trouble, and yes that means the everfree forest too."

First off why the fuck would applejack even consider saying yes to that question and then afterwards telling apple bloom to not go near literally the only place in ponyville you could find monsters?

"Spike nodded and retorted in a somewhat pleading but also sarcastic way. "Well, why do you let me carry thjem around all day then if they are that important, and why do i have to carry them all?" Twilight giggled at that, one giggle that made Alex feel very uncomfortable. "Well thats because you are my number one assistant after all right? And why we brought them, you have no need to know, it's not like a dragon, let alone a small baby dragon would understand that right? Now stand back up before i drag you home to show you what happens to dragons who don't behave accordingly!"

I understand one of the mechanics of your story if not the defining one is racial inequality but that's a little bit excessive

Aside from some other spelling and grammatical issues it's not bad
At some point it would be a good idea to get an editor

Also one more thing

"Alex...you surely are not in Cansas anymore...."

I think you can figure out the problem with that
