" Thriving" at the expense of someone else, or allowing someone else to thrive at your expense.

以牺牲别人为代价的“繁荣”，或者允许别人以牺牲你为代价的繁荣。

But we can and we must also recognize when we're advantaged at the expense of someone else, and recognize fairness as the balance between these two inequalities, because our society literally depends upon it.

但是我们可以而且我们也必须认识到我们何时以牺牲他人为代价获得优势， 并认识到公平是这两种不平等之间的平衡，因为我们的社会确实依赖于它。
