Sen. Bernie Sanders has introduced a bill to implement a 5% wealth tax on billionaires, which has attracted support from government employee unions. The proposed tax revenue would fund new federal spending programs, potentially leading to growth in the public sector and union membership. Critics argue the plan is more about expanding government and union power than addressing wealth inequality.

Why it matters

The wealth tax proposal is seen as a litmus test for Democratic presidential candidates, highlighting the ideological divisions within the party. It also reflects the longstanding relationship between government growth and the interests of public-sector unions, who stand to benefit from the increased federal spending.

The details

Sanders' wealth tax bill would levy a 5% tax on the net worth of billionaires, with the projected $4.4 trillion in revenue over a decade earmarked for new federal programs. Critics argue this creates an incentive for unions and the government to expand, as more federal jobs and union-eligible positions would be created, leading to an increase in union dues. Even if the tax revenues fall short, the new government programs would likely remain, furthering the growth of the public sector.

• Sen. Bernie Sanders introduced the wealth tax bill in early 2026.
