I think the key to Saturn's rings at least is accretion discs. I.e the material that makes up both the planet and its discs was a rotating mass before the planet formed.

Once rotating, the equator of a body has a larger circumference than one that passes through each of the poles. This then helps to keep the rings bound to the same plane as the equator.

Not sure about galaxies or solar systems though - however I suspect that similar forces are at play.

On a side note, while looking for an answer I discovered that one of Saturn's moons is emitting some 1000kg/s of water vapour from it's South pole, which is then ionized and rotates around Saturn. Neat stuff. ThanksThumbs Up | :thumbsup: http://en.wikipedia.org/wiki/Magnetosphere_of_Saturn[^]
