It's called supply and demand. There are less clients available then that there are freelancers.
Edit: Actually this might not be a 100% correct. Its easier for clients to do a Google search for freelancers than it is for freelancers to do a Google search for clients. I.e. freelancers always pull the short end, meaning it's not easy for freelancers to be picky about clients...
If you can produce work that people love, it's absolutely imperative that you work with the best clients because not only will you get 10x pay, but those clients will propel you forward by virtue of supplying you with better quality projects, and the cycle continues.
That said, while great guys and gals can call the shots, those who aren't confident in their work (often, due to the mediocre quality of the work), end up settling for the average or below client. However, even then, if a freelancer is truly serious about improving her work, then she ought to seek out the best client, for the reasons stated above. IMHO
