Insurance companies make a simple wager with you each time you sign a policy. They are betting that, over the life of the policy, they will pay out less to you and your beneficiaries than you will pay them.
Insurance companies of all kinds make tidy profits on this simple wager. If they don’t, sometimes the government will bail them out.
Either way, insurance is still just a bet. And in America, we do not have a healthcare system. We have a health insurance industry.
