We haven't been, and whether you think it's the chicken or the egg, immigration lawyers specializing in H1-B and related visas have made a mockery of the law and of the stated intent of those visas.
If you read the letter of the law it's perfectly reasonable. And when highly credentialed specialists who are truly unique talents get visas to work here, the results are beneficial to everyone.
But as a result of intensive lawyering, thousands of mid engineers get mid jobs at mid pay and are exploited like indentured servants.
If the letter of the visa laws was actually enforced, we would not have this problem. To which the lawyers will say we're just doing our jobs and doing it well.
