I've already stated them many times.

- The league has effectively doubled in size in terms of roster spots
- Integration alone has a huge effect on the talent pool.
- Population has boomed; easily more than doubled.
- Rich become richer / poor become poorer - MLB draws from the poor.
- Medical advances allow people to play who previously would not be able to - replace John Smoltz, Kerry Wood, and a multitude of other Tommy John surgery recepients with the best players in the minors. Do the same for hitters with torn ACL's... you get the idea.
