There's a difference between things that are caused by outside sources and things that are caused by bad decisions. Bidens handlers made some really bad decisions like shutting down drilling for oil which resulted in high gas prices throughout his presidency.
- The U.S. government funds federally recognized tribes and Native American programs mainly through annual discretionary appropriations and some mandatory spending compiled in the OMB Native American Funding Crosscut, totaling roughly $30–37 billion in recent years (with additional multi-year infrastructure funding).
- Health care is the largest category via the Indian Health Service (around $7–8+ billion annually), which funds direct services and tribally operated facilities for eligible American Indians and Alaska Natives.
- The Bureau of Indian Affairs and Bureau of Indian Education (Interior) provide several billion dollars for tribal government operations, public safety, natural resources, trust land management, and schools.
- Other major streams come from Education Department programs (Impact Aid, tribal colleges, Head Start), HUD housing and community development block grants, USDA nutrition programs, DOJ justice support, and smaller set-asides across agencies such as EPA and DOT.
- Most funding is delivered through direct federal services or through contracts and compacts that let tribes administer the programs themselves under the Indian Self-Determination and Education Assistance Act.
So they don't get a direct payment from the federal government but they are highly subsidized.
