We don’t even operate the Fed gov on a BUDGET. Paul Ryan just GIVES x-trillions to Obama based on what Obama wants (called the Omnibus Spending Bill-—we haven’t had budgets in a while thanks to Republicans). I am sure that in a real BUDGET we could scrape together a fraction of what Obama GAVE Iran, for example.
Imagine cutting all useless departments, eliminating fraud and waste, stopping all foreign aid, and eliminating the UN. Probably save a million bucks a year per capita
What is lacking is will, not cash.
