H1B people are favored by some businesses because they can get away w/paying them less.
So even if a relatively high paid H1B exists, their US counterparts make more.
Correction from A Silicon Valley FReper who's been-there-done-that: The US counterpart does NOT make more, because the US counterpart is UNEMPLOYED.
The dastardly H1B program caused and continues to cause massive unemployment for US engineers, because the Indians coming in _displace_ them, NOT "supplement" them.
