I'm often asked whether campaigning for fair tax can make a difference. I believe it does. This is some small evidence form the Guardian:

A leading City fund manager considered pulling an investment in Amazon from its ethical funds because of the online seller's tax avoidance measures and its employment conditions for its staff around the world.

Royal London Asset Management (RLAM), which bought Co-operative Asset Management last year, revealed it had written to the online retailer demanding clarity on its tax levels and where its tax was paid around the world.

Would this have happened without tax campaigning? No, of course not.

It's not much, but it's an indication of change. That's progress.
