I was in Cupertino a few months ago at a meeting with Apple. Beautiful facilities with 10 asian folks representing Apple and two Americans. The Americans were the lawyer and the marketing guy. All these asians were extremely well paid with great facilities, free food, they owned great cars. I saw no slavery. I also saw no technical Americans either.
The technical Americans where fired after they trained the Asians. The Lawyers would be fired if they could be replaced by H1B1 holders as well.
