I recently discovered h1bdata.info. Super cool. I was digging around looking at consulting companies that have a huge number of H1Bs and found an employee at Wipro who apparently makes $200M a year. He's listed as a "programmer analyst". The CEO of Wipro makes about $1.5M a year. What's going on here? You can see Wipro's H1B applications here and sort by salary: http://h1bdata.info/index.php?em=WIPRO+LIMITED
The other interesting thing I noticed is that small town of Bentonville, AR is apparently a major hub for H1B IT workers. Lots of consulting companies list hundreds of people there.
