I can't overstate how sad it would be if the goal of this change was plainly to stick to to Democrat states. It there is truly do much disdain that didn't boat well for the future as a united country.
The entire tax bill seems to be sticking it to Democrat states, in particular New York and California, but it is really about urban vs. rural politics. Democrats have become too concentrated as a party in urban areas and so rural voters have gotten enough political power to attempt to address what they view as economic inequities in the current urban/rural income distribution. Republican have also flipped the script…
1. As already mentioned, it helps ultra-wealthy and people in red states at the expense of the blue states. But by crippling the tech economy, the govt. would harm their own long-term ability to collect tax revenue to invest in other states. Right now, CA provides more tax revenue than it takes back and this money pays for federal govt. projects elsewhere.
2. Many people would get bankrupted simply by vesting. It's one thing to tax people once they have money. But most options are not liquid. Many people would simply not have money to pay for options that they cannot sell and will not be able to wait for some hypothetical IPO or buyout.
Let's just be honest about what this is: it's a vindictive and cynical move to harm the economies in blue states and only marginally help those in red states, and then only in short term (until the tech economy in the US contracts and moves elsewhere).
If this passes, I hope those who support it enjoy their feeling of revenge, because that's all they'll end up with. The rest of us in tech sector will just find another place to grow our business.
