Oh yeah for sure I am not disputing that this is the way that the system works - the whole thing rests on the compromise point between the employer's margin and the employee's wage. Both need each other to some degree and so a compromise is reached which is the market value of labour.

That said, other models of system are available - worker coops and other models of employee-owned business can and do exist. They have their own merits and flaws though - nothing in this world is perfect.
