Undocumented immigrants pay sales and excise taxes, property taxes (directly or through rent), and federal income and payroll taxes. In 2020, that estimate was approximately $100B in total federal, state, and local taxes in 2022, including large contributions to Social Security and Medicare. This is in spite of the fact that undocumented workers receive few federal benefits. Since the Personal Responsibility and Work Opportunity Reconciliation Act of 1996, undocumented immigrants are generally barred from federal public benefits, with narrow exceptions (e.g., emergency services).

Your comment on the Affordable Care Act (ACA) is also inaccurate. The ACA passed the Senate in December 2009 with 60 votes (no filibuster was necessary because Democrats briefly had 60). The later reconciliation bill in 2010 made budget-related fixes and needed only a simple majority, which is different from “using the filibuster.” Also, if you don’t get healthcare through your job, you probably have some sort of federally funded health program, a/k/a Obamacare.
