Wait. You're comparing total cost in France, to cost at the point of use excluding taxes in the US. Education in public in-state universities is also highly subsidized.
Those state subsidies have steadily been eroded over the time period under discussion--part of why tuition has increased. At most large state flagships, public funding is now a significant minority of revenue.
Right. But you still can't compare US price without subsidies to French price with subsidies. They are still a significant minority, about 30-40% of what Tuition brings in.
Besides, public funding given a year ago still factors into costs today.
Sure. But what I'm wondering is what subsidies you're referring to. Are you talking about grants and loans that students get, or maybe federal grant money for research?
