That said, this post is crafted marketing nonsense.
For example, a statement like this from a company founder is ridiculous: "In fact, the restrictions on H-1B visas make that entire topic moot since highly skilled talent must meet strict wage requirements set by the US government based on prevailing wages in the county you're hiring the person into, in the skill-level and profession of that person."
Let's be real here. Every big bank and insurance company has battalions of "Senior Programmer/Analysts" churning out J2EE for $35k/year or less. "Prevailing wage" is a term of art that doesn't mean what it sounds like it ought to.
