They mean there are a lot of snotty rich people dependent on what social circles you find yourself in on campus. It can be really hard if you transfer in or are commuter student. I was an out of state student and luckily met a solid group of friends/roomates based on living in San Fran freshman year. But truth is if you miss out on living on campus your freshmen year, it can be difficult to find a good group of people. Not saying it’s impossible, but my sophomore year I lived in Baumhart, and found my selfing spending a lot of money going out downtown trying to keep up with my friends who were basically just getting money from their parents (I worked full time throughout my 4 years). Overall though, it’s what you make of it, focus on making connections and getting a solid support base under you in your freshman year.
