Start with the agencies- defund them, abolish many. The EPA and Dept of Educ can go immediately. Repeal all protections for the unions- the taxpayer will no longer be responsible for their benefit packages. End grants to the arts and NPR. No more grants to university “research”. Abolish all government “corporations”.
See? Easy!
Those are tiny drops in the bucket. Medicare and SS are the big money. End those, quickly.
