There is a reason that other nations in the Anglosphere do not have anything close to such a tax — even as they spend in a way that would appeal to Ocasio-Cortez — and that is that such taxes do not really do much good. Most people who make tens of millions of dollars rarely derive the lion’s share of their money from traditional income — and, should such a bracket be added to the books, the few who do would quickly restructure. The top tax rates in comparable Anglosphere countries such as Britain, Canada, Australia, and New Zealand are 45 percent, 33 percent (federal), 45 percent, and 33 percent respectively. There is no 70 percent rate in any of those countries — on millionaires, on billionaires, or otherwise. Hell, there is no 50 percent rate, either.
This is not to say that there is no difference between the way that those nations operate and the United States operates. On the contrary: Unlike the United States, those nations do have much higher taxes — on their middle classes.
Why? Well, because that’s where the money is. The U.K.’s 40 percent tax rate kicks in at just $59,178 (I’ve adjusted for U.S. dollars, here and below), and its 45 percent rate starts at just $191,521. In addition, Britain has a 20 percent value-added tax that makes pretty much everything annoyingly expensive. Australia charges 32.5 percent at $26,377, 37 percent at $64,162, and 45 percent at $128,324. New Zealand’s top rate of 33 percent is levied on earnings above $47,319, while Canada charges 26 percent after $69,794, and 33 percent after $154,153 (this is on top of considerable provincial income taxes).
If the Democratic party wants the United States to be more like its Anglosphere cousins, it needs to stop talking stupidly about “the rich,” and begin making the case for the considerably higher middle-class taxes that will be needed to pay for the considerably higher social spending it covets. Thus far, Democrats have done no such thing. Instead, Democratic aspirants point excitedly at the health-care systems and family-leave policies of Britain or Canada, while promising not to raise taxes on anyone making $250,000 or less per year. This is an impossible, unsustainable combination.
