First: nobody is forced to get a graduate degree. In many fields (like programming), it's nothing like a requirement to earnings maximization. Since grad students already have degrees, they are also free to work and save until they can pay for fees outright or reduce their loan burden.
I don't have total stats in front of me, but it looks like the Law/Medical/Business schools are ~50% of graduate employment at Harvard. Take it as read that these are worth borrowing for.
The other 50% -- AFAIK there is a significant portion of students on fellowships/scholarships of some kind. My guess is very few people are taking on a bunch of debt for a Divinity PhD.
At this point, it's fair to say that Harvard offers better financial value at all levels for its programs than many public universities offer their in-state residents.
It's interesting that so many replies function on these kind of assumptions when I am telling HN my literal experience at an Ivy League postgraduate program. I received two of the available three fellowships one could compete for. They covered less than 5% of tuition overall. Six figures of debt was the norm for my program.
Now of course, as you said, no one is forced to get a degree in humanities or what have you, but my point is that if you make expertise in these fields contingent on massive, insurmountable debt, you impoverish the culture.
You've hinted at your experience without providing details (even the school or the type of graduate program). I obviously can't comment on your situation because I know nothing about it. I am literally assuming nothing about your experience.
I do know other Harvard grads (both undergraduate and grad programs) and have some insight into their situations. They don't have "massive, insurmountable debt." Anecdata abound.
I vigorously agree with your last point.
As a result the people I know from the time who went on to graduate degrees all had free rides (except the MFAs, who I admit are a mystery to me, and the people who went back for MBAs later).
All that I said I do agree we shouldn't be burdening our youth with crippling student debt. But the idea that our culture comes from our humanities departments seems a little absurd and not supported by evidence.
There are also fields where a doctorate is the entry level qualification like biotech, materials science etc. even in the private sector, but that's what happens when a there are more than ten times as many PhDs producer as there are academic jobs for.
However, it's a long slog without a big money payoff after graduation, in fact it is better to be a student in most cases.
My parents could've paid for my college education with some sacrifice (I paid for it, but they could have done so financially) if it were just me going to college. But I have two younger sisters, and there's no way they could cover all three of us.
Additionally, any parent can simply refuse to hand over tax returns and the child is left having to pay 100 percent of the costs.
Harvard's endowment is ~$40 billion right now. They're solvent.
So in reality it's not need blind.

"The Harvard College financial aid program requires no contribution from Harvard families with annual incomes below $65,000; asks from 0 to 10% of income for those with incomes up to $150,000; and expects proportionally more from families with incomes above $150,000."
If your family makes <$150k, it sounds like Harvard costs up to about as much as the (public) University of Minnesota charges in-state residents. (Depending on your situation, Harvard may cost substantially less.) If you borrowed half of the $15k annually (the max 10% of $150k income), that's not an insane burden when paid over 30 years.
This seems fairly balanced. Granted they could zero out fees for families further up the income scale, but on the other hand "rich kids go to Harvard free" is maybe not the best use of the money.
