Let's talk: there is nothing to fear from a level playing field for taxes
Being on the right side of history is important.
When there are huge global forces moving in a certain direction, it's crucial that a country and the Establishment of the country recognize this - and do something about it. In terms of the way large corporations avoid tax, the world is moving in a certain direction. People will look back in years to come and be astounded at the way corporations were able to play countries off each other in order to avoid tax.
The world is moving towards a level playing field in the area of corporate tax. Earlier this year, US President Barack Obama described American companies that use foreign countries to avoid US taxes as "corporate deserters". This is serious language.
