Yeah I get you but say you're a software multinational and you've got an employee that takes home a grand a week. If the tax rate goes up you're not going to get them down to €8.65 an hour, even if you reduce their salary it's still going to be comfortably above what the minimum wage is. The only way that a reduction in the minimum wage is likely to have a serious impact on salaries as a proportion of expendature for multinationals that might be here is if we start doing sweatshop manfacturing and tried to take on Aisa.
Take into consideration that if our corp tax rises to a point where the uk is a nicer option for these jobs it doesn't take much imagination to move the building to newry or belfast. then the impact on salaries is huge. also see above post above to show how on average a savvy multination can have two employee's on average less then 8.65 per hour at present.
