I wouldn't say the ones I know are too cheap. They're all grad students (mostly in pharm or biotech), but because they're students they can only work 20 hours a week, and the only places that will hire them are PT on-campus places like my work, so they're making minimum wage, and the rent here is, for example, $1300 for a 1BR, so they have to live 4-6 people or they can't pay to live here.
Some of them live more comfortable but they move into the crime-ridden neighborhoods of the city.
