According to a Harvard study, an estimated 45,000 people die every single year because they don't get proper healthcare coverage or don't have healthcare insurance at all. The for-profit insurance industry makes money off of people's misery and illness. It denies coverage to many when they request that a doctor or medical provider try a lower cost option first. If they had their way, we would still be living in an era where insurance companies could deny healthcare to human beings on the basis of preexisting conditions.
I don't condone the use of violence against another human being. I don't wish death upon United Healthcare CEO Brian Thompson or any insurance executive. The fact of the matter is though, they wish death upon thousands of people each year when they deny them coverage or seek to profit off of the healthcare conditions and ailments of others. They have turned wellness and taking care of yourself into a profit seeking industry and made billions off of people's sickness and injuries.
So when you mourn the passing of Brian Thompson, also mourn the tens-of-thousands of people who die each year because this country doesn't provide a universal system of healthcare. Mourn for all the people past and present who have suffered and died because they were denied coverage on the basis of a preexisting condition of some type by an insurance company. Mourn the people who were denied a certain treatment or medication because their insurance provider refused to cover it or said they needed to try a cheaper option first.
