But by the time they go to the ER it's too late. People with insurance go for regular checkups that will catch things early. Those without will only go to the ER when their situation is desperate.
Perhaps you misunderstood my comment. Many uninsured in the US go to the hospital ER for minor care, such as for colds and other temporarily ailments. I suspect that these sort of cases far outnumber the visits involving serious care cases.
you would be surprised how many with insurance don't go or don't listen to their doctor. it has nothing to do with insurance and more to do with fear or just laziness
