I would probably choose to pay the higher amount - I'm happy to pay a reasonable amount of tax, and am disappointed at the more and more widely held assumption that we would choose only to contribute as we are legally obliged, rather than morally motivated.It’s not the companies fault, it’s the system that allows it. Unfortunately it’s normally those that set the system that benefit from it!
Honestly though, if the options available to you were to continue paying tax as you have been paying or legally paying just a fraction of that amount, who would choose to pay the higher amount?
