>so can be said as a fact that lower tuition fees increase the number of students from poorer families. Correlation does not imply causation. In Spain, jobs that did not require a university degree were paying really well before the crisis, so many people were joining the labor force at a young age instead of going to university. From my observations, this was specially prevalent among people that came from less educated families. Suppose that at the same time university fees were going up (I'm not sure about this). In that scenario, if you looked at the data, you could wrongly conclude that rising tuition fees were discouraging people with less educated backgrounds from attending university.
