Most Americans don't realize just how huge and extensive medicare/medicaid is. They cover 65mil and 88mil people respectively, including 40mil children. That's 153mil people out of 330mil population -- that's 46% of the USA's population. Total spending is $1.9T for both. A cost of $12,400/person covered. $1.9T is 7.5% of the total US GDP of $25.44T. Medicare/medicaid is a massive program. Bigger than social security at $1.4T. It's crazy huge.
