Such as? What other mechanism makes it possible to pay 700 billions per year to the private sector for something that the taxpayer can't see, because it's secret?
Medicare for All would cost well over $4 trillion per year according to the Lancet. That would be going to privatized hospitals, doctors, big pharma, medical consultants, supplies, equipment, diagnostics, lab companies etc...
But I would point out to you that the military's budget is $700B regardless of whether the US is engaged in foreign armed conflict or not, and half of that is personnel costs like salary and housing allowance. Only about $300B goes to procurement of all types (weapons, clothing, food, cleaning supplies, fuel, paint, etc...)
