Because a creature with CR 10 has to kill other creatures with CR 10 in order to get proportionally the same experience as a 1st level character killing CR 1 creatures. Now, there are lots of CR 1s just about everywhere, but not so many CR 10s, and very few CR 20s. People in D&D worlds face CR 1s even if they don't want to, but they have to be adventurers in order to meet CR 10s, and have to search quite hard for CR 20s.
Therefore, it is much easier for members of weak races to gain a few levels. A 1st level party has to kill 13 orcs to become 2nd level. A CR 23 red dragon has to kill how many balors and pit fiends? I mean, they don't grow on trees. And after doing in half of the Nine Hells hierarchy, he's got, what, ONE level?
Mind ya, I still love and use monsters with levels. But the way I see it, a Human Fighter 8th could be just a good army officer, while a Frost Giant Fighter 8th is a freakin' legend. Mostly, I give levels to outsiders and immortal creatures in general, figuring that if you've lived, say, 20000 years, gaining levels is just a matter of statistics. Incidentally, this is also the reason for which I kinda like the idea of outsiders being relatively weak, rather than the powerful monsters of today. That way, I can reasonably give them some levels without making them into epic challenges.
