I see where people are coming from when they dismiss high marginal rates out of hand, without giving the honest answer as to why: No-one who is caught by them will pay them. If I'm Michael Dell, and my marginal rate is 70%, or 90% or even 100% (whatever) then I'm incentivized to take that money in another way, be it in stock, deferred bonuses, or even in leaving the capital in the business without issuing a dividend. The reason this is such a problem is that regardless of whether you manage to close every conceivable loophole, you're still talking about personal taxes. The corporation is making the lion's share of the money, and that's where the tax would need to be applied to raise the revenues required by the Green New Deal. Thing is, that's never worked for a state because the biggest companies are multi-national corporations that can (and do) shift their taxable income to the most favourable jurisdictions, which is why nation states keep trying to undercut each other on CT rates (Apple and Google are notorious for the lengths they go to in order to avail of this, for example). The state can't close that kind of loophole because it doesn't have the authority to (unless it goes down the road of sanctioning other countries due to their tax rates). I've not seen a solution to wealth distribution yet that acknowledges that we exist in a global economy, regardless of local policies (however well intentioned they are). Thing is, most people don't really seem to want wealth re-distribution to anyone poorer than them. Unless you're planning to pay a living wage to everyone in India/Thailand/China/wherever then why shouldn't they undercut your taxation rates as much as is needed to attract local jobs?
