A progressive wealth tax has benefits as well. I just think there's value in pointing out the impact that such a small percentage has. Implementing even a fraction of a percentage would make a serious impact; we don't need to go whole hog right here, right now.
My ideal starting point for a progressive wealth tax would max out at 2%, because that's within a standard deviation of annual S&P growth.
I understand the perspective that the extreme wealth taxes wouldn't change the quality of life of the ultra-rich... but do you know what the long term impact on the economy would be?
I don't. And I study this kind of thing. This is not the kind of system that responds well to massive, overnight changes. Most Americans get their food by buying it... if we fuck up, and the economy irretrievably crumbles without a backup, people will starve.
As desperate as people may be for radical change, it is worth it to make these proposals in a responsible way, and ensure that we're not doing more harm than good.
Here's my pitch:
You have a package go missing, and you don't know why. It shows as delivered, but you never saw it. You check the ring camera to see what happened to it, and one of your kids picked it up, took it inside, forgot about it, and when you asked, was too dumb to piece together, "Oh, THAT package."
