Ever noticed how the Borg is like a termite mount?
You got your worker termites slaving away for the good of the colony.
the only one with any importance is the queen. (the board of directors)
All the individuals slave away as one. They think as one and act as one. Individual, outside the colony thinking means instant death.
They don't know why they just do. Individuals are of no significance and are readily sacrificed for the good of the colony.
The colony must survive at any cost.
