Top tier blackpill in the comments.
It's actually common sense, I laugh when I hear cucktears say the blackpill is a bunch of nonsense conjured by incels when it's clearly observable reality.
We all win or lose the genetic lottery at birth. Sure, you can influence your appearance and health, but if you're dealt a sufficiently bad hand you can still be screwed insofar as good looks are concerned.
And good looking people are perceived as not just more attractive but more capable and more trustworthy, and people want to please them, so they get a much easier ride through life in some respects. I'd quote studies, but I can't be arsed, and those studies that show this are out there.
When you constantly get those advantages then of course life will feel fair. It's perfectly fair that you're leading a charmed life compared to your uglier counterparts, and said uglier counterparts won't be nearly as apt to think life is fair as they receive lower salaries, fewer opportunities both career wise and romance wise.
There are certainly some downsides to beauty - beautiful women (and to some extent men) will constantly be hounded by people who want to experience that beauty firsthand, and that sometimes takes really nasty turns. But overall, good looking people who win the genetic lottery get huge advantages in life. So of course life will feel more fair - they far more rarely lose.
