Yeah, we rented our apartment in Brooklyn NY in 1989, and none of the outlets were polarized.
Then my parents bought their co-op in 1995, and the same thing was there, all outlets were very old and non-polarized.

Of course, a highrise building, carpet/wood floors, no grounded structures nearby.
Kitchen is an entire different matter. I do not remember if there were outlets with a GND pin there, and how the fridge was plugged in.

I do remember that back on Russia, when our fridge was touched, one would feel a little "bite", as we called it. Not a real jolt, but unpleasant stinging sensation.
