I hate this question. Most of our country is ignorant of how many government agencies there are, much less what they do. There are many agencies we could cut completely, but some keep your lights on, your railways and canals functioning, and the GPS in your car online.
Cut fat and keep the meat.
Cut Congress' salaries and benefits. They hardly ever work and when they do? It's not what we voted for - which IS THEIR JOB!
ZERO TAX DOLLARS TO ILLEGAL IMMIGRANTS OR REFUGEES. ZERO.
Municipal: Everything except water, garbage, sewage, fire, police, and road maintenance.
Federal: Everything except the powers explicitly granted it under the Constitution.
Welfare. Every penny. Set up a system where churches, Synagogues, and mosques are 100% responsible for all largesse. Incl doctors.
Needs to be a M-F primary purpose for God's Houses [Catholic Masses are offered every day; take it one step beyond ♥]
