Not me, but I can tell you why I would pay more taxes.
For one, having health care tied to a job is a big burden. As an employee, it makes choosing to leave my job extremely worrisome, especially if the federal government repeals the pre-existing conditions portion of the ACA. I can never leave my job while I am sick, or my kids are sick.
Tying your health care to work also makes it harder to start a small business. You need to offer your employees health care to compete for good workers, but it costs a lot more per employee for a small company to get insurance than for a big company (a big company can get a better deal because they have a larger cohort).
An even more insidious fact of employer based health care is that it doesn't cost the same for everyone. If I am going to hire someone and offer health care, it will be MUCH more expensive for an employer if the person is going to have their children and/or spouse covered as well. It will cost more if they are older. It will cost more if they have medical conditions.
This adds a perverse incentive to employers to favor hiring younger, single, people. As an employer, I should not be worried about the marital and familial status of my employee. I should pay them the salary we agree to. There are laws against discriminating against some of these groups, but if you are a small company it makes a huge difference to your bottom line.
I also fear getting a major illness. Suppose I am doing everything right, working and I have health insurance. I get cancer, and it is treatable, but it might take years to beat. I start out fine, with my good insurance. One year in, it becomes clear I can't keep working my job, so I am let go. I can keep paying for my own insurance through COBRA, but my savings are dwindling because I am no longer working. Even if I am suddenly able to work again, I wouldn't be able to get new insurance because of my pre-existing condition.
There is literally NO amount of planning I could have done to avoid this situation. I was doing everything right, and an illness can make you go bankrupt.
The last argument for why I would pay more for health insurance is a moral one. I find it immoral to not provide basic health care to everyone. I feel it is an obligation we have to each other, and the most efficient way to meet that obligation is through a single payer system. Insurance works best with the largest possible pool of people to spread the risk, and you can't get a larger pool than everyone.
So yes, I am willing to pay a little more for a single payer system, for both selfish and altruistic reasons.
