Taxing unrealized capital gains sounds really bad which is why they chose it to be their big policy talking point this week. It didn't sound quite right to me, so I looked into it a bit. I'm not that savvy when it comes to this shit, but my take is anyone freaking out about it is either exponentially more wealthy than the people deciding this election or has been told to freak out about it and doesn't understand shit about fuck.
Not only is there a massive cutoff for assets, it sounds like there is a liquidity requirement, possibly 80%, meaning that the unrealized gains are being borrowed against to effectively gain liquid capital while avoiding the steep capital gains taxes. This sounds like one of these band-aid attempts to patch a loophole that would be a pain in the ass for the corporate accountants for a year or so until they find a new weakness in the tax code to exploit.
I agree with the concept of taxing loans on unrealized capital gains, but this idea is probably ineffective and a nonstarter on Congress. It's also not new, and Kamala hasn't to put anything out specifically in support of it. But it's absolutely a nada-burger for the any of the people complaining about it on Facebook or wherever.
