The abundance of uranium and thorium is of the same magnitude. The thing is economics. Uranium is cheap, and as long it is, we use the sources we have. As the peice of uranium rises other sources get economical including sea water extraction which is effectively renewable.

Uranium is a much scarcer source compared to thorium. Uranium can also be used to create nuclear weapons, that's why other countries have difficulties using the tech because foreign powers are afraid of these consequences
