If you mean the difference between the top line capital gains vs income tax rates, I generally agree but also understand the math does not.

You could reset realized long term capital gains taxes to match income tomorrow and it would not be a huge material difference in the budget. I am 100% for doing this anyways simply because it’s fucking absurd any professional W2 employee is paying more percentage in taxes vs someone who just happens to have idle cash at hand - but it’s more of a “social contract” thing for me than actual tax policy.

The issue really is tax deferral strategies and wealthy folks being able to consistently find strategies to roll over investment dollars into new investments without ever having their gains be subject to pretty much any tax. Stuff like stock buybacks, tax loss harvesting, 1031 exchanges etc.

I don’t think the “loans against a stock portfolio” tax dodge thing is nearly as large as social media decided to pretend it is - but I am very much in favor of taxing any realized value at regular capital gains rates at the time of realization. This means you will probably need to sell a bit of an asset to pay the taxes - which is the entire point.

Unrealized gains are tricky. I’ve been in a situation as a bootstrapped startup founder where I owed “phantom” tax on money I had not yet realized and ended up taking a loss on years later. Zero ability to recover those taxes paid. It put me into a hole for over half a decade. This gives huge preference to those with existing wealth and makes it even harder for someone with nothing to “come up” without handing out a majority share of their company/idea to idle capital. Especially if you’re just doing regular economy things to create a small business doing boring stuff at single digit net margins.
