Please correct me if I'm wrong, but isn't there an offshore influence that aids in dragging down both US salaries as well as hourly consulting rates??

US companies will always hold this over our heads right??

If Americans ask too much, won't US companies simply go offshore, or tap into their L1 visa pool to lower salaries and/or hourly rates??

Why is the offshore influence not taken into account in your article??

This is a constant issue, but anything written by anyone concerning the US job picture must absolutely take into account offshore factors. Am I asking the right questions, or am I off base on this??
