MLB, NCAA, NFHS Payments

[PAT THE REF]

Hello all,
I was thinking today about how much do the "professional umpires" get paid per game? Does anyone know how much MLB or NCAA officials recieve per game? Is there a diffrence between NL and AL? Just was wondering.....
I was also passed over a website a while ago and it talked about whether or not an umpire could live on his/her salary..... Any idea's on that?

Any information would help - Thank you
