You forgot to mention the private schools are expensive and use a somewhat pyramidal scheme where older students teach newer ones to repaid part of their school fees. In public education all teachers hold PhD or engineer titles so they have more years to think about what they teach than the guy who is only year+2 of the teachee.
Edit: I checked Epitech tuition fees, it's around 40k€ for the whole 5 years curriculum. You can make a century of studies for the same price in any public university.
