That should be a new thread.
Military - all bases in Europe and other places where they are no longer needed.
Action in Libya. Afghanistand in about a year, and Iraq in about a year too cut by half or more.
Medicaid - becomes a states program so federal funds get cut 100%
Medicare - each person can opt out of the system or pay more into the system as they like. If they opt out they get a refund to put into a retirement account and will have earned interest equivalent to what they would get if they stayed in (not much) if they want to pay more, because rich folks do not pay in as much as poor folks as a percentage of their income then they get coverage that follows the principle "you get what you pay for"
Social Security - everyone gets back an equivalent of what they have paid in unless they want to stick it out.
Almost all other federal programs, like education, returned to the states.
Remaining programs cut by a straight percentage.
Eliminate any loopholes for the rich.
Stop all corporate welfare.
Tax every single person at the same rate and give every single person the same deductions and allowances. The rate would be "regressive" and the deductions and allowances would be "progressive". The end result would be a tax system that was neither regressive nor progressive.
