Why are you bringing "fairness" as an excuse ? There's no such thing as fairness, Sasuke understood the value of hard work way before Naruto because he wasn't self-obsessed with not being liked.
He wanted to be like Itachi because he wasn't recognized by his own father and he didn't let that stop him from working on his jutsu until he eventually was. Meanwhile Naruto was throwing tantrums waiting for someone to hold his hand even though the Hokage was there to guide him.
Secondly, you're wrong about Naruto not asking for power, he was born with Ashura's chakra since day 1. In addition, Sasuke wasn't born with power, he was born with potential like Naruto, and his hard work and determination to surpass Itachi is the reason he fulfilled it.
His Sharingan was never free, first he had to witness the death of his parent, then he had to sacrifice himself to save Naruto against Haku before re-awakening his dojutsu. Meanwhile all Naruto had to learn was draw out chakra to use Kurama's power.
Kurama's power was never trying to destroy Naruto, the bijuu only wanted to free himself and Naruto's emotions simply allowed his body to be taken over. He was no different to Sasuke who ended up having his mind taken over by the emotion emitted from a Sharingan.
And you seem to forget what Sasuke went through before having Itachi's eyes. He was training under Orochimaru while Naruto was only roaming the country with Jiraiya.
Secondly, he had to face Deidara before fighting Itachi and nearly died because of that. I don't care whether Itachi was already sick, Sasuke had to use his full power to push his brother to his limits.
Thirdly, Obito refused to give him Itachi's eyes until Sasuke gained enough experience with the Mangekyo. And guess how he did it ? By facing a perfect Jin and fighting 5 Kages. So how is that not hard work ?
Furthermore, before gaining EMS he was already capable of fighting a bijuu 1v1 with his own Mangekyo, the same Mangekyo he worked hard to unlock. And you seem to be the clown as the manga clearly shows the bijuu giving Naruto their chakra, which allowed him to awaken RSM in the first place.
