Putting a billionaire tax avoider in charge of the Treasury is like making Pablo Escobar the Minister for Justice.
Did the issue of the green card ever get cleared up or do we have a Prime Minister who is wanted by American law enforcement?
It isn't sexist to criticise Rishi over this because if he didn't want his wife's finances to be considered jointly with his then he shouldn't have entered into a legal contract with her.
It isn't racist to criticise Rishi over this because, IIRC, the people of India would have quite liked his wife to pay taxes there, too; instead of, where was it? Mauritius? The Cayman Islands?
The argument that it isn't against the law doesn't wash as he's one of the people who makes the laws, and he doesn't appear to be changing any of the ones that benefit rich tax avoiders. If it's legal it's because he wants it to be legal.
The argument that it's sensible financial planning makes it sound like he's saving up for a motorhome or dreaming of an early retirement to the Algarve. He's got oligarch-level money. Once you're in the realm of hundreds of millions, going out of your way to cling on to every penny is just greed. What was he financially planning for? What was he going to have to go without if he didn't keep his wealth in a tax haven?
Rory Stewart has said that when he was Prisons Minister he tried to persuade Rishi that non-payment of council tax or television licence fines shouldn't lead to custodial sentences, but Rishi wasn't having it. If you're too poor to pay tax, he would happily send you to prison. If you're so rich that you could pay tens of millions in tax and never even notice it, he'll make sure you can hoard your wealth offshore.
He's part of the problem. He's part of the world's financial corruption.
