Re: probably not enough
You're right, the issue is not the tax laws of countries but the very lax transfer pricing regulations (not laws) that exist.
And it's not just an European problem.
Micr0$oft "licences" the right to sell Micr0$oft products in the USA to Micr0$oft Puerto Rico for about $8Billion, Micr0$oft Puerto Rico then sells Micr0$oft product to the 'merkins for $16Billion, effectivelly off-shoring $8Billion profit to Puerto Rico.
The last time I bought a Micr0$oft product I paid a UK company for a CD for a product that was that shipped from Germany to Ireland.
Of course the real issue is not that companies are actually doing this, but how did the laws get set up??
Bloomberg claims that the "grand architect" of the double Irish Dutch sandwich is Feargal O’Rourke who heads the tax practice at Price Waterhouse Coopers in Ireland, he is a member of the O’Rourke/Lenihan political dynasty in Ireland and at one point in time was advisor to his cousin, the late Brian Lenihan, former Irish minister of finance. According to bloomberg "He advises both multinational companies and the government on tax policy and has emerged as his country’s leading defender".
