Thank you. That point wasn't made clear in the article, and as a non-Washingtonian, I didn't know that income taxes were unconstitutional in your state.
They are trying to say it is “Not” an income tax because the earner is not paying it, but the payer is. It’s just legally pretzelizing the whole thing.
All they have to do is get the voters to pass the concept of an income tax, at any low level, then they can just raise it at will. But out of human decency they should leave the voters enough to be able to afford the KY jelly to reduce the pain.
