Eh, true wealthy people are against a tax that hurts them, but that doesn't mean that their argument is without merit. Think about what a wealth tax means. Say I found a company like WeWork (bear with me and try to forget the shenanigans pulled by their CEO). Things are going pretty well and before you know it, we raise money at a $200 million valuation and my stake is 50%. On paper I'm now worth $100 million dollars, but that money isn't in my bank account... it's an imaginary number that my investors decided to invest at. Based on E. Warren's wealth tax plan, I now owe 2% of my wealth above $50M. So where do I get that $1 million from? I don't have cash or liquid assets, so likely I have to dilute my shares to get some personal money. No problem... investors will understand. So I go on for a few years paying some taxes on my new wealth, 3-5% of my equity a year. Now, the company has grown and we raise a big amount of money. Say Softbank gives us $5 billion at a $20 billion valuation, and i've been diluted to 25% at this point, but now I'm worth $5 billion on paper. Under EW's plan, I owe 3% of my wealth above $1 billion, plus 2% of wealth between 50M and 1B. My tax bill is gonna be $139,000,000. Again, my wealth doesn't exist in the bank... it's in my private shares. But okay, I raise money from investors to dilute my shares and pay taxes... at this point they expect it. OK... now I make plans to take my company public. Finally I'll have some real liquid money and paying these taxes will be easier, because I can just sell shares on the open market. But wait, I put some feelers out and the market thinks my company isn't worth $20 billion... it thinks it's worth $10 billion. Do I get a refund for past tax payments? The point is that the government will have a very hard time determining what things are worth. It's easy to tax income or sales, because those are known values. The price of WeWork, or a Picasso for that matter are not. So what's gonna happen? I can guarantee that billionaires are gonna come up with a 1000 ways to claim that they are worth much less than they are. They'll start taking companies private. They'll put money into hard-to-value and illiquid assets. Some will revoke their citizenship and move elsewhere. On the whole, it may not gonna be great for the economy, even though in a sense there's a moral justness to it. There are better ways to tax the wealthy. Higher capital gains taxes and estate taxes to name a few (estate taxes run into the same issues as wealth taxes, but at least it doesn't burden people to value their property every year).
