Why does a long extension cord drop voltage measurably, but every home in the US gets 110V power, regardless of distance?

I can't figure out why putting my microwave at the end of a long extension cord changes its performance noticeably, but everyone seems to get the same service to their home, no matter where it is.

Wire has resistance. A long thin wire will drop voltage in proportion to the amount of current that's flowing.

Power is distributed to homes at a high voltage and low current until it gets to the last transformer, and the voltage is adjusted along the way to compensate for losses.
