Larry and Sergey can’t stay in California since the wealth tax as written would confiscate 50% of their Alphabet shares.

Each own ~3% of Alphabet's stock, worth about $120 billion each at today's ~$4 trillion market cap.

But because their shares have 10x voting power, the SEIU-UHW California billionaire tax would treat them as owning 30% of Alphabet (3% × 10 = 30%). That means each founder's taxable wealth would be $1.2 trillion.

A 5% wealth tax on $1.2 trillion = $60 billion tax bill, each.

That's 50% of their actual Alphabet holdings—wiped out by a "5%" tax.

Section 50303(c)(3)(C) of the 2026 Billionaire Tax Act states: "For any interests that confer voting or other direct control rights, the percentage of the business entity owned by the taxpayer shall be presumed to be not less than the taxpayer's percentage of the overall voting or other direct control rights."

This means if a founder holds shares representing only 3% of economic interest but 30% of voting control (through Class B supervoting shares), the tax would presume their ownership stake is at least 30% for valuation purposes, not 3%.

The wealth tax is poorly defined and designed to drive tech innovation out of California.Image
The law is so poorly written. While the lawyers who drafted it claim it doesn’t apply to publicly traded shares, they designed a legal trap where Class B voting shares would count as private shares and therefore considered ownership.

It’s so dishonest. Image
The specific tell is this passage in the text: “provisions of this Part shall be liberally construed to effectuate its purposes”

In other words capture as much tax as possible

These clauses were the work of Professor Darien Shanske at UC Davis Law.

This is shoddy legal work that seems to be meant to destroy tech in California. There are so many other ways to tax the debt some billionaires use to fund their lives, as Bill Ackman proposed.

I can’t help but mention there are many efforts afoot to try to destroy tech and innovation in California and San Francisco

Late last year there was an effort to ban hard tech labs in SF’s Mission Districg: literally the birthplace of GPT-1 and self driving cars

This CA “billionaire” tax is an unrealized gains tax. A unicorn startup founder becomes a paper billionaire around $5B val. At YC we avg 2 to 4 per year (!)

This will kill startups and innovation in California since a founder is illiquid while instantly on the hook for $100M
Fast growing startups grow up to be major tech firms. California benefits from tech creating prosperity massively.

But the money is massively misspent and somehow special interest groups are pushing to kill the golden goose of tech. Image
This is coming from the same place as SF Supervisor Jackie Fielder who recently tried to ban R&D and laboratories (including cancer research and AI research) in her district.

They hate tech so much they want us to leave. But we will vote them out instead. Image

PSA notice to founders considering YC

Doing YC more than pays for the 7% equity you give up

When you combine that with the clear speed up and community that helps you (and that your % likelihood of success goes up a lot more too) this means YC is clearly worth it Image
The “avg ARR” stat is completely useless as a metric because the vast majority of YC startups start with just an idea or with no revenue. This means the vast majority of ARR at YC demo day pitches was done in 10 weeks

Your avg non-YC deal has revenue from 10 months not 10 weeks
Objects in motion stay in motion.

Objects at rest stay at rest.

Net net as an investor you want to be in the startup that grows fast (slope) instead of has a high ARR number (y intercept)

Basic and obvious

San Francisco schools is trying its absolute hardest to make sure all middle income families who could move out of the city do so right away

“Grading for Equity” is going to be a real disaster and I guess this is a boon for SF private schools and Burlingame housing prices Image

For education bureaucrats who ruin our public schools with the most unfair and anti-merit polices: BUSINESS IS BOOMING

Someone needs to investigate the Schools of Education that spawn these policies because it is a real danger to public schools everywhere

Maximum Karen energy

The wife of the creator of Farmville pictured below doxxed my home address and forced me to move because I got politically active

Let’s work hard to vote out their favored elected officials and root out their corrupt cronies
In 2019 The Richmond Democratic Club honored her with some kind of award alongside Peter Lauterborn, a manager in the SF Ethics Dept

Having friends in the Ethics dept is awfully handy if your political machine might need the dept to look the other way

This was the same event with a truly rotten cast of corrupt politicians including Allison Collins who was recalled for making instruction worse for kids, removed Algebra from middle schools and merit from Lowell (and calling Asians house n-words)

The difference between an overhyped startup failure and a valuable real business that makes it the long haul is sometimes as simple as:

Do the founders themselves believe in what they are doing to the point where they will not quit?
This is where definite optimism matters: If startup ideas were people…

an indefinite optimist looks for more optionality, searching around the room at the party for the more interesting person to talk to. Image
A definite optimist engages deeply and finds themselves engrossed in the person they are talking to now.

For their startup, the problem or way to solve becomes a calling. It isn’t just words to trick people into giving them capital or to come work for them.
