Universal Healthcare Sounds Great. Here's What's Happening in Countries That Have It.

"Free healthcare is cool," comedian Shane Gillis recently said on The Joe Rogan Experience. "We should have that."

"You should treat the entire country like it's a community," Rogan replied. "If you had a community, would you want the sickest person to fucking die who could be very valuable if you could take care of them, and do you have the resources to take care of them?"

While support for "free" healthcare in the United States is not new—Harry Truman campaigned on universal health insurance in 1948, and Sen. Bernie Sanders (I–Vt.) has popularized the "Medicare For All" slogan in recent years—the policy has received renewed interest of late. The Democratic Socialists of America have made universal healthcare "at no cost to individuals" a key component of their party's expensive platform.

But it is not just political hopefuls who like the idea of universal healthcare; academics seem to as well. A recent study by the Yale School of Public Health claims that single-payer universal healthcare would save more than 100,000 lives a year, and would supposedly cost $1 trillion less than the system it would replace. The study, which has not been peer-reviewed yet, appears to come to its conclusions by modeling a scenario that assumes cheaper pharmaceutical prices, less administrative overhead, reduced fraud, and fewer emergency visits.

But we do not need modeling of unrealistic scenarios to see what universal healthcare could do for Americans; we just need to look at countries that have already implemented this system.
