> US yearly spending on welfare systems: $1.80 Trillion

And maybe people should think and ask why is so much being spent with so little getting to the bottom? Medicare / Medicaid cost almost 2 Trillion USD / year. But when you will look on prices of i.e. Insulin, which is simple drug available outside of USA for 10EUR but in USA it costs 300USD out of pocket without Medicare. Now it makes sense why you got 2T in the budget when Medicare is paying for 100 years old drug like it would be a latest cancer treatment.

There's no insulin that is 100 years old that diabetics use. The insulin used is of many types and all these types have been developed over the 100 years you seem to ignore, and new ones are still being developed. You can now buy inhaled insulin. There's rapid acting and medium and fast and super fast and there's mixes developed for certain patient groups.
