Both usually rank quite well in various international comparisons.
The US has a great healthcare system, but abysmal health insurance.
The US Health insurance industry spends on average, 86% of premiums on healthcare costs[0], which means they can increase their profits by reducing those costs, since 80% is the floor.
12% of the left over premium gets spent on operating expenses, which leaves the industry with a 2-3% profit margin[0]. So another way of increasing profits is for the companies to become more efficient.
These figures are for the industry as a whole. Any individual company will have other avenues of increasing profit, such as growing their market share.
