And yes, there are other options for solving problems like that beyond just a wealth tax, but maybe a wealth tax is part of the solution.

But...it's not? The only person who has concentrated an unimaginable amount of wealth for which this might be true is Jeff Bezos's Amazon, except Amazon workers all earn a $15 minimum wage, 401k matching, and are part of the same group health insurance plan as the engineers and product managers. They happen to enjoy some of the best health insurance available to an entry level job that requires no college education.
Outside of Bezos, the vast majority of the wealthy pay their workers handsomely (Bloomberg, Bill Gates, Tim Cook, Page/Brin/Pichai).
And even if this was somehow a pervasive truth, the solution to that is a basic income, not a wealth tax. A wealth tax wouldn't even come remotely close to funding a basic income. If you were to seize 100% of all wealth of the top Forbes 500, you would get enough money to run the current Federal government for 8 months. Not 8 months per year, 8 months ONE TIME.
Capitalism is a fantastic means for directing economic forces as long as everybody has enough capital to do the voting, as it were. If only a few people hold all the capital, then only a few people make decisions and will often engage in capital strikes rather than risk the chance that their position may be threatened.
I just read Progress and Poverty by Henry George and he makes this point very clearly. I highly recommend giving this book a read if you haven't yet.
This feels like a fallacy
Correct, they grow out of having a middle class with purchasing power, who can buy products and services, thus creating jobs for those who provide those things. But the middle class's effective purchasing has been going down for decades, while the wealth at the top has been increasing. So something needs to be done to balance these flows of capital - the current situation is not sustainable.
If the problem is middle class purchasing power, then the solution should be to directly improve middle class purchasing power (via a UBI).
And no, a wealth tax will not come remotely close to funding a UBI.
