California's public-sector unions have established a substantial political influence, amassing over $1 billion in dues and fees in the fiscal year ending 2024. This financial engine is fueled by the state's robust tax system, which includes a 63-cent per gallon gas tax and sales taxes exceeding 10% in some areas, alongside high marginal income tax rates for top earners.

The growth in state revenue directly correlates with an increase in public-sector workers, leading to more union members, higher dues, and greater power for union leadership. These unions, in turn, advocate for increased taxes and state spending, creating a cyclical reinforcement of their influence.

Collectively, 10 of the largest California-based unions with public-sector members reported more than $1 billion in dues and fees. These organizations represent over 1 million members, constituting a significant voting bloc, potentially swaying statewide elections. Members' dues are a primary revenue source, with some unions also directing funds towards political campaigns and lobbying efforts. Many employ in-house "political organizers" to advance their agendas.

This financial structure allows unions to achieve a high return on investment. For instance, the California Teachers Association spent $2.1 million to lobby for a $10 billion school construction bond. Upon its passage, the increased funding for new schools indirectly benefits union members through higher salaries and more hiring, at an estimated taxpayer cost of $18 billion after bond interest.

Unions have also actively pushed for new revenue streams. SEIU's United Health Care Workers–West (UHW) sponsored Proposition 40, a proposed tax on the assets of billionaires, with proceeds intended for health care services like Medi-Cal, a program where UHW members are employed.

The state faces fiscal challenges, with a projected $14 billion structural deficit for 2026-27, exacerbated by significant unfunded pension liabilities exceeding $265 billion. Unions have consistently responded to fiscal concerns by advocating for increased revenue generation.

The dynamic described positions public-sector unions as a dominant political force, capable of securing programs, tax commitments, and employment categories that require opponents to consistently mobilize to maintain the status quo. The technology sector is identified as a remaining private power center with the financial capacity to challenge this influence. The article suggests that the proposed wealth tax serves as a critical juncture for the technology sector, representing the last major base not yet fully influenced by the union machine.
