I was recently watching a PBS special about quantum physics and they asked why do electrons have mass. I found myself unable to answer this, although I am only in high school physics, but could any of you answer this? Thanks.

We don't comlpetelly undersant why ANYTHiNG has mass, that is one of the things they are trying to understand at LHC (they will be looking for the Higgs boson).
Although I don't quite understand why you are asking specifically about the electron? In this respect the electron is no different than any other particle (proton, neutron etc).
 
A better question would be, why does the electron have the mass that is has?

If it didn't have mass the universe wouldn't be as it is.
