Opinion: Can the U.S. healthcare system be fixed?

No country in the world spends more on healthcare than the United States, or has less to show for it when compared to other wealthy nations. The U.S. spends nearly 50 percent more per capita than Switzerland, the second biggest spender among wealthy nations, but consistently ranks near the bottom on measures of population wellness and life expectancy. Is there a better system, and if so, what should it look like? What role does wasteful spending play in this equation?
