Immigration and the cap

I have had a thought that has been bungling my head now for some time, naturally in the current PC climate I have not uttered it for fear of character assassination and impending fathwas. It would appear that businesses think that the current cap is hurting their profits rather than helping them

The Government's immigration cap is facing fresh pressure after evidence from one of its own business advisory committees shows the damage it is doing to UK businesses.

Okay, so the 101 is that businesses want to bring in more cheap labour so that they do not have pay, admittedly, the astronomical costs associated with employing a British person. And since it is such an imperative, apparently, to bring in that cheap labour then why are they even bothering with having the business in the UK in the first place, if they are not going to employ British people? Surely if it is such a burden on them why not simply relocate and they do not have to pay the government imposed ridicule that constitutes the frankly affronting percentages that has become NI. Not to mention the soon to be raised income tax.

UK business have known for some time that this country does simply not produce cutting-edge graduates anymore, since we appear hell bound on becoming a third-world country on par with Zimbabwe. With this in mind it would seem easier to just relocate than to whine-down the government for attempting to stem the ridiculous levels of immigration seen under New Labour. They too must know that it is not politically expedient for the government to backtrack on anything remotely related to immigration.
