A slave is a person which is simultaneously property. To all those that believe having a "shitty job" is slavery, may I ask you to identify the corresponding master/owner?
Its usually someone running a business, the usual suspect. If you are a wageslave you are fucked... not much margin of action. If you are not part of the initial distribution of the pie and your family didnt got a nice slice of the pie, then you'll need something special. Most people aren't and its difficult to break the wageslave loophole.
