Everyone has access basic preventative care regardless of income
No one goes bankrupt due to medical costs
No one has to wait until a medical condition is serious enough to seek emergency medical care which drives up costs for everybody
No billions of dollars a year spent on costs unrelated to health care like Shkreli profits, insurance company profits, and billing and administrative costs
Save money spent on useless things that don't help anybody, spend it instead on things that help people. Make medicine regardless of whether a rich investor thinks curing a disease is profitable.
