Oh I hate this bullshit hypocrisy about ti only being sensible and practical that Bono reduces his tax bill.
He has spoken out about the injustice in the way the world economic system is organised. It is utterly hypocritical of him, not to speak out about how the tax systems in rich developed countries, are organised so that the richest, most powerful people in those countries, can minimise their tax liabilities in a way that simply isn't possible for poor people in those countries. The rich have sown up tax systems in individual nation states, in exactly the same way as they've sown up trading and economic relations on a global basis. If he doesn't get that connection, he's thick.
And not to speak out on it, but to actually take advantage of it, instead of saying: "I'm rich, I can afford to pay taxes, everybody who is rich should and actually we should have a more progressive system so that poor people don't pay a proportionately higher percentage of their taxes than rich people do", is so incredibly hypocritical. It's like saying "the world trade system means that we rich white westerners benefit, we should take full advantage of it and get even lower coffee prices" but he doesn't does he, he says let's change the system because it's unfair. He can see the systemic injustice in one and rail against it, but he takes full advantage of the systemic injustice in the other. That's what makes him such a ludicrous figure.
