I think corporation tax is a totally different matter to personal tax. The more you tax a company the more you limit it’s ability to expand and create. Fair enough, that might not hold on the mega billions world of Apple, but there isn’t a whole heap of them.
No one actually benefits from a company making money. It is very, very hard to get money out of a profitable company without paying a fortune in tax. So once a government do tax the money they are either a) just reducing what they would get anyway when the directors go to take the money or b) hampering the ability of the company to expand.
Yes, it’s different when the money isn’t actually really earned in Ireland. But in that case I would just treat it as every cent got is a bonus and not worry about what we don’t get.
