Not necessarily true about being self employed. I currently work with a contractor who is a self proprietor with an EIN he uses for tax purposes to itemize his business expenses for the work we do. He works for staffing companies who find him work for business in trade specific jobs such as fitting, welding, and shipbuilding around the world, and doesn't stay with one specific staffing company. Granted, he doesn't use an individual 401k for retirement or any 401k for that matter, but he is still considered self employed even though he draws a W2 every year.
