Why is Cuba so great?

The passage in this article caught my attention.

Excerpt

The secret love affair between left-leaning elites and Cuba goes on no matter what. No sooner had Cuba's aging Fidel Castro resigned, tha a common narrative emerged in liberal papers like the New York Times: positive changes could be coming to the hemisphere's last bastion of communism.

On Cuba's northeast coast, meanwhile, 24 ordinary Cubans -- men, women, and children -- boarded a boat under cover of darkness. They set off across the Florida Strait to America -- presumably unaware of the media's upbeat Cuba narrative playing out in the country of their dreams. They landed in South Florida, reported the Miami Herald.

My question. Why are these people risking their lives to come to the US? Don't they know they have a far superior health care system in Cuba than we do?

It's one of the things I've always questioned about "progressives". Why is it they want to make our country, the greatest country in the history of humanity, more like a country where people are willing to die to leave.

It sure isn't the government health care.
