I will happily do so. Bear in mind I used Google and Gemini to help me find the sources and summarize the numbers, so take that for what you will.
First the problem is the definition of "productive allocation of resources". If you're a billionaire, either inherited or building a tech startup, that money goes to things that create new businesses, and your wealth is the reward of investing your time, energy, and resources into others. Very few billionaires can become one without average people buying what they're offering, be it rent from real estate or social media posts; the only exceptions are lawyers or finance people. The other hard part is it's not quite apples to apples; business people create jobs through their companies, whereas governments provide social safety nets to try and lift people out of difficult situations. Both can create jobs, but in very different ways and for people facing very different situations.
What we do know is that the California tech ecosystem, entrepreneurs deploy capital very quickly, creating jobs very fast. But by California's own data, the tech ecosystem now has 1.8M jobs in California, which is 9% of the State's workforce, but accounts for 19% of California's entire Gross Regional Product at $623B per year. On top of that, some older studies show that high tech employment is a net job multiplier; it is calculated that every tech job results in 4.3 jobs in services and local goods. Another estimate says that California's tech sector directly and indirectly supports 4.2M jobs, or 20% of the entire workforce statewide. That's with roughly a $150B and $200B annual deployment of capital. Notably, that capital comes from two sources, revenue generation (which also generates taxes, but is essentially lost as an expense) and investment. The investment part is key because the money isn't lost; while the money gets spent by the company, the source of the funds is the value retained by the investor, who often trickles money back to the money managers who backed the VC, and those money managers are often pension funds and insurance companies who serve individual needs.
Now let's look at the State Legislature. The annual budget of California hovers around $300B annually. They fund payrolls for state employees like teachers and various safety nets. Public sector job multipliers are around 1.3 to 1.5X. So right there, the tech sector where most billionaires are located, use fewer dollars to deploy into high paying jobs that have a statistical knock-on effect of creating 3 extra jobs for every tech engineer hired, whereas state employees create 1 extra job for every state employee job.
So there is one metric, backed by studies, showing that with less resources (around $200B spend annually) 4 jobs are created or maintained vs. the State budget which spends $300B annually but only 1.3-1.5 jobs are created or maintained.
But the bigger issue, and one of the key sources of why governments do not deploy capital efficiently, is the stated purpose of this tax. It is, per the SEIU who sponsored this, a one-time, emergency 5% tax to prevent the collapse of Californai healthcare and help fund California public K-14 education and state assistance food programs. Along with a bunch of other outright salesy stuff about how only 200 people will pay the tax who have $2 trillion. Sounds good for poor voters right?
The problem is, they're seizing assets to pay for expenses. This one-time tax will fund issues for 5 years; ok. What happens at the end of 5 years? The problems in education and health programs and food assistance are still there. Further, you practically guarantee capital flight. One study shows that with the billionaires who have already relocated ahead of the deadline, California has lost out on $2.7B in recurring annual tax revenue. Six have already left (Steven Spielberg, Larry Page, Sergey Brin, Peter Thiel, David Sacks and others), but many others are considering leaving. This tax, if passed, is retroactive back to Jan 1st, 2026, but that may be entirely unconstitutional. So you can be sure this will be litigated up the Supreme Court, costing California tax payers more money before they collect on the fund. The tax bill will also remove an existing cap of .4% on "taxes on intangible and personal property", making this an entirely new tax and would allow for unlimited future wealth taxes; the government will have every right to extend this down to the middle class, including personal homes and going around Prop 13. So absolutely the State Legislature could raise property taxes if this bill passes because it is a Constitutional Amendment, and they would not need to to voters at all.
So how's that for allocation fo resources, plus sources and the like? You can refute the studies by being partisan, sure, but you can't change the facts. Six billionaires left California before the tax went into play for a direct loss of 2.7B in annual revenue, and many more will leave. They will challenge it in court, creating issues before they collect. In the meantime, those people will be spending money outside of California, creating those jobs elsewhere, whereas more people are going to need social safety benefits as their jobs move to other states right when California is losing tax payer dollars.
