"charge everywhere on the wire remains constant" - perhaps. But the charge is still flowing, it's still moving at a rate of dQ/t. What is dQ/t you may ask? It's the time derivative of charge. It's the change in charge over time, the rate of flow of charge. I=Q/t Current=Charge/Time Amps=Coulombs/Second I don't know how to make this clearer.
