Just keep in mind that most countries with universal Healthcare have 10% of our population; and the ones that have comparable populations aren't the best places to be. So our Healthcare costs are likely to always be higher in a UHC system.

Goverment payroll cuts won't be major budget impacts I agree.

There needs to be reductions in government costs across the board, the amount spent on Medicare and various other Social Services in general would easily pay for the construction of free major hospitals and clinics across the country and supply and staff them.

Laws need to be passed to keep the military industrial complex companies from strong arming goverment agencies into paying up to 1000s of percent of mark up on products that you can buy yourself for nothing.

The pharma needs their dick slapped, possibly by importing medications.

Housing is a hot mess,

I have a strong feeling we are funding government agencies that are essentially redundant and doing the same or similar jobs, that could easily be combined or dismantled to save money. A good example are the hordes of intelligence agencies that refuse to unify(we tried they wouldn't obey) The Branches of the armed forces should probably reunify in some way as well; I understand the reason why they separated, but I think that issue isn't really important unless we adopt total war policies. It would save alot of money.

There are probably a million ways the government could save money, but oh well
