The tuition rate for any public university in France (for EU citizens) is €250/year. So your tuition was not 100x, it was just 44x what you'd pay for those.
Let's say that's unfair, since the state pays your tuition (though this is the common experience for most French students!). In Amsterdam, one of the best universities in the world, TU Delft, charges €2k/year tuition. Your tuition was less than 10x this, true, but not that far from that. Also, for a common 4 year bachelor's degree, that's €8k in total - your $100k total is more than 10x this.
