Elon Musk has proposed an ambitious initiative to reduce the US federal budget by at least $2 trillion. This would require implementing unprecedented austerity measures similar to those seen after World War II.
Achieving such a significant budget reduction would likely involve substantial cuts to widely supported entitlement programs such as Social Security, Medicare, Medicaid, and veterans' benefits.
The feasibility of implementing such drastic changes in the current political and economic climate is a subject of debate.
