Who benefits from Tier 2 Changes?

If Vince Cable the Business Secretary believes the caps are liable to effect British Business, with companies moving their projects offshore http://www.telegraph.co.uk/finance/economics/8009872/Number-10-attacks-Vince-Cable-over-immigration-cap-claims.html  and John Cridland deputy director-general of the CBI saying in the same article: "The interim cap is causing serious problems for many firms. The figures used were artificially low as they were based on numbers at the height of the recession in 2009."As firms are gearing up for growth, some are finding that they are only able to use a handful of non-EU specialist staff."

and Chris Huhne the Energy Secretary further criticising the cap: http://www.globalvisas.com/news/more_friendly_fires_attack_coalition_s_immigration_cap2630.html

and Boris Johnson saying much the same thing: http://www.bbc.co.uk/news/uk-politics-11275354

Why are these caps being imposed and who exactly will benefit from them?

These aren't opinions coming from the labour party but from within the government itself.  The general consensus at least from a business perspective is that this cap and the mooted changes to the Tier 2 Work Permit system will negatively affect the economic recovery. So why exactly impose it? Reason being that part of the government’s pledges to the electorate was that they would reduce net migration. A veritable political hot potato. The interesting statistics to note are that of non-EU migration numbers  the majority of visas issued are for students http://www.bbc.co.uk/news/uk-11094468  rather than Tier 2 or Tier 1. The other non-EU figure of note is the Inter Company Transfer figure, another area that to date has not been targeted by the MAC.

The UK and more notably London is an international business centre, attracting the brightest and the best, both companies and workers. Does the average British voter really want these businesses to move overseas? Talented individuals generating income and paying tax elsewhere? If the system truly is 'out of control' then why not attack the areas that are being exploited; students visas, illegal immigrants and ICT's? The answer it would seem is that reducing the number of Tier 1 and Tier 2 visas is simply easier to impose. Reduce net migration and be able to say that they have fulfilled their promise to the electorate. <sarcasm>Visionary politicking.</sarcasm>
