> But more broadly, taxing the rich costs nothing
It does though.
1. As one of "the rich" that progressives target continuously, I still can't afford a house in CA. I'm moving to Washington and CA will lose many median Californians' worth of income.
2. Nearly every EU country that attempted wealth taxes (another form of "taxing the rich") recalled them due to capital flight that offset the tax income.
3. California has passed the peak of its Laffer curve, where higher taxes don't provide higher returns due to capital flight. https://www.ipi.org/ipi_issues/detail/californias-laffer-cur...
4. I personally don't feel the value in working harder or smarter to earn more, because the marginal returns are so low due to taxes. Discouraging innovation is not good for the country.
> We can progressively tax all to symbolize something about economic fairness
Despite the common memes the US has one of the most progressive tax systems in the world. https://manhattan.institute/article/correcting-the-top-10-ta...
Anyways, "taxing the rich" simply doesn't get us there:
1. You could liquidate every billionaire, including all their assets, and you wouldn't fund the government for 9 months.
2. The rest of us that progressives consider "rich" are W-2s that already pay a fuckton in taxes. If you look at the sources above, this is explained clearly.
3. Contrary to the meme, the biggest objective gap in tax income is not on the rich but on our middle class, which does not pay its fair share wrt our EU counterparts (explaining the gap necessary to fund the desired social services, which taxing the rich would not cover due to its comparatively small size). 40% of Americans pay no federal income tax! https://freakonomics.com/podcast/ten-myths-about-the-u-s-tax...

Finally, at the core of your assumption is the idea that more taxes help. As someone that has worked in both government-funded labs and government contracting, I can promise you they don't. The sheer wastage is mind boggling, honestly sickening. It makes the our tech mega corps look tiny. I used to have a progressive view on taxation until I saw the infinite money black hole that was government spending.
