Some major U.S. corporations including Tesla, Disney, and Citigroup have paid zero federal income tax in recent years while spending millions combined on lobbying and campaign contributions. This creates what tax researchers call a 'self-reinforcing loop' — corporate money influences policy that allows them to minimize tax liability, then they spend that saved money on politics. The broader context that would strengthen this argument: how many of these companies received federal contracts, subsidies, or tax credits during the same period, which would show the full cost to taxpayers beyond just income tax avoidance.
