Ultimately, in a physical, absolute sense, nobody is entitled to anything. The universe does not care about your sense or morality, fairness, or sociopolitical views.
In a universe that is catastrophically unfair, thinking about "who deserves what" will drive you insane. Obviously we all have our own ideals and values, but ultimately they don't matter.
I have advantages and disadvantages over others, yet in both cases they were just given to me. I did nothing "right" or "wrong" to deserve them. I have freedoms that most of the world doesn't have simply by virtue of being born in America. I was born in a time period where I could buy things that increase my quality of life that people born centuries or even decades before me didn't have access to. And on the other hand I'm ugly, low IQ, have a severely botched circumcision, and brain damage. I was subjected to all of these things against my will either by nature and/or other people and those things (especially the low IQ, and ugliness) have had a lot of downstream effects and imposed very restrictive bottlenecks. It's why I work in fast food at nearly 40 and live in a shitty apartment in a shitty area with roommates.
I could have been born a pretty boy from a rich family in beverly hills, or I could have been born a 1/10 in rural india with no electricity, much less internet. Or even worse, I could have been born in the UK. I swear seeing the retarded laws that get passed over there makes me love my country more and more. Shout out to my nigga George Washington. And speaking of George Washington, if we lost the revolutionary war, he would be remembered as a terrorist or a war criminal, because the winners write the history books.
Which brings me to my next point, might makes right. I'm not saying that's a good thing, but that's the way the universe works.
Nature > power/authority > the law > everything else.
The only way to make the world fair (and entitlement stems from a sense of fairness) would be to make everyone exactly the same in every conceivable way, which is obviously impossible even in theory. Though I suppose human extinction would make us all equal since we'd all be dead, which is ultimately why some incels are praying for a giant comet or nuclear war.
