The fact that you work together should be the biggest deterrent. If things don't work out, you still have to see each other and work together every day. I work with a couple who are going through this very thing right now. The company has a policy against dating a co-worker, but they'd been keeping it on the quiet from the managers. Last weekend they broke up. She's so upset she can barely work and he's constantly pissed off and talking trash about her to all of the other employees.
A person who lacks education does not necessarily lack of intelligence. My husband never went to college. He got married and started having kids. He wanted to go to school, but had to put that aside and make a living to support his family. He ended up divorced. I met him and suggested he follow his dream of getting into medicine. He got a 2 year nursing degree, then a bachelor's degree and is now working on his masters to be a Nurse Practitioner (and is getting straight A's, by the way). If I had written him off because I had a college degree and he didn't, neither one of us would be where we are today.
As far as race and social class, that's a question only you and your prejudices can answer. If you are from a culture that forbids or even frowns upon dating outside your race or social class, you have to contend with what your friends, your family and society in general would think of you, even if you personally can accept the differences.
