I don't disagree, but we're already spending a lot of money on the masses. 3.3T on entitlements to 800B of military in 2019.
Spending Review
Reducing military by 50% is barely a 10% increase to entitlement spend.
I prefer the wisdom of Patrick Ewing here, "People complain that
pro athletes the USA makes a lot of money; but what they don't understand is that we need a lot of money because we spend a lot of money."
When you look at military spend as a % of GDP, we're not in the
top-20. Of the countries you listed we're already spending less as a % of GDP than Russia and Saudi Arabia and
cutting military spend by 50% would put us behind China and India.
