Why is the Oort Cloud spherical in shape and not a disk along the solar plane like the Kuiper Belt?

Given time, most objects due to angular momentum, become restricted to some form of plane, the galactic plane, the solar plane, etc. Does the spherical shape of the Oort Cloud suggest that it is relatively young?

It's because the Oort Cloud is so massive and vast that the Sun's influence on it is relatively small at those distances, and other stars and the galaxy overall are also able to influence the motion of the objects. The outer limits of the Oort Cloud are ~1/4 of the distance to Proxima Centauri, for example. 

The *inner* Oort cloud *is* roughly disk-shaped, but the farther you get from the Sun, the more spherical it becomes as the absolute gravitational domination by the Sun diminishes.
