Ground and neutral are supposed to be connected together at the transformer. That's why there's never a substantial potential difference between ground and neutral. Incidentally, "every half cycle the voltage goes the other way" has nothing to do with it. It reverses polarity, but it's still connected across exactly the same wires. The power for your house comes out of a 220-volt-center-tapped transformer winding with the center tap grounded, and connected to Neutral. Live is _either_ of the other 2 transformer wires, depending on which circuit of your house you happen to be looking at.
