Why does a boost have a higher output voltage than a load current?
Since the output voltage of a boost is always greater than the input voltage, the input current must be greater than the load current. This is a simple consequence of conservation of energy: the input power will be equal to the output power plus the losses. In this case the losses are taken care of by the efficiency factor, η.
