From Iron Knee at Political Irony:
Most Americans who have health insurance get it through their employer. I have started several companies and served as a CEO, and I can assure you that if a company didn’t have to spend the time or money providing health insurance — something that is a huge distraction and money sink from the company’s core business — then that company could easily afford to pay their employees a significantly higher salary. In fact, typically enough to more than offset the extra taxes that people would have to pay to support universal single-payer health insurance.
And there are other benefits that most people don’t even realize. For example, I have lived in three countries that have single payer systems, and in those countries insurance for your car is a small fraction of what it is in the US. Why? Because the biggest cost of car insurance is liability insurance to cover health care costs for you, your passengers, and other parties when you are involved in an accident. But if everyone’s health costs are covered by a single payer system, then there is no need for that insurance.
