If your net take-home pay goes up (or even stays the same), why would you care if the line item called "CA tax" goes up while the line item called "health insurance payment" goes to zero?
Because my line item - insurance payment is only $2350 out of pocket me for the year, the tax hike according to what we make (delta to our current taxes) would equate to a years worth of mortgage payments, which is a gigantic difference. In addition california already has a low income health plan called "covered california" so low income families are already covered without the need for doubling taxes.
I am certain that your "insurance payment" is missing out on the portion that your employer is paying. The big tax increase that the headline is talking about includes that. If you look at your paystub you can find the total cost, and I am sure you will be shocked at the number, it is very likely over the costs we are talking about here.
The headline hints that families would be paying those additional taxes, but if you read the details most of the additional taxes are on companies (and the best points that the article makes are about how those are structured in ways that may not make sense). They are trying to mislead you to be outraged in the headline, and it worked.
So the taxes that you and your employer pay would increase (that is what the headline is saying), but much if not all of that would be offset by the costs that you and your employer are currently paying.
If your net take-home pay goes up (or even stays the same), why would you care if the line item called "CA tax" goes up while the line item called "health insurance payment" goes to zero?
