like someone else said, students ..mostly men don't want to look like they're broke so they can attract sexy chicks at school. So they have the nice clothes + the nice car.
Here's what you should be worried about:
How many of those who have the recent cars+expensive clothes have good grades. I'd just guess that most of them barely go to school/don't give a shit about school and are there just to socialize and get pussy.
You have a bunch of different categories of big spenders at school.
1. The guy who wants pussy and show other males that he's better than them and doesn't care about grades so he works all the time, has money just like any other working man would and then goes to school to basically show off. He is pissed about tuition fees because he is actually paying for something he doesn't care for.
2. The guy who's been broke all his life and now wants to feel rich to get some pussy and show other males he's better than them so he gets himself deep into debt to afford a 15000$ car and 2000$ worth of new clothes every month. He's pissed about the tuition fees because he's already in debt and tuition is adding more and more and more on his back.
3. The guy who works a few hours a week, doesn't pay for food, doesn't pay for tuition, doesn't pay for his books because his parents are paying that. Which means he can put his earning towards a car and clothes to look good and get some pussy and show other males he's better than them. In the end, he's pissed about tuition fees because his parents are coming down on him telling him "dude, pay your tuition yourself, it's starting to get expensive and you spend on your money on shit you don't need". so he wants tuition fees to be lower so his parents stop yapping.
4. There's also the rich kid, they don't give a fuck about the tuition fees. They're rich.
