It's hard for me to believe there exist companies that have the resources to hire software developers and that don't use source control.

You better start believing it, I've seen it... If you doubt my anecdata, check TheDailyWTF.

It seems to me that the problem is too many people see software development as linear and quality as monotonically increasing, i.e. just save your work and back it up.
