This is kind of an interesting paradox. Using the waterflow analogy, your statement makes sense. However, if you were to insert a resistor in the ground side of the circuit, and then if you were to measure the voltage drop across that resistor, you would find that the "current" (V divided by R) on the "ground" side is exactly the same as it is across the original load. This suggests that circuits are "the same", no matter where you place your measuring device, which suggests that there is no real difference between the ground side and the hot side, in terms of electron flow. Of course, another way to look at it would be to say that after adding the resistor, the "ground" side of the circuit consists of the connection between the newly installed resistor and the negative node of the circuit, but you can add an infinite number of resistors in series, and the current will always be the same.
