Think of it like this. Imagine three people wanting to look over a fence to see a parade: a short person, a middling person and a tall person. If we find a box of exactly the same size for each of them to stand on, then the short person still can't see over the fence, and the tall person has a great view. That's "fair" because we made sure each of them had the same size box — but the short person is left staring at the fence.
Then imagine if we gave two boxes to the short person, and the tall person just stood on the ground. Each person could see the parade because we made sure that we took their individual needs into account. That's being fair, too.
So which sort of fairness is best? Treating everyone exactly the same or treating people according to their needs? The right of politics prefers people to be treated the same. The left thinks we ought to take some account of individual needs so everyone can get a fair go.
I hope at least some of her students have the wits to point out that height is an accident of birth. I am myself the person who would need two boxes to see over the fence.
But in real life I've never be needy in terms of tax redistribution because before marriage I was almost constantly employed. After marriage we had children we could afford, didn't spend what we didn't have, and have stayed together.
Some degree of good fortune, maybe. But where people fall in the "individual needs" stakes is very much influenced by factors within their control. Unlike race, gender or ... height.
