Yes. There are a great many of us who have jobs that either don't offer health care or have insurance plans that still make it difficult if not impossible to afford medical costs. We tend to fall in the cracks, making too much to qualify for assistance, but not enough to pay the bills. It's not that we don't contribute, we do. And it benefits everyone in the end, by having a healthier population overall, which improves our lives and allows us to miss fewer days of work. This helps increase the economy overall. Countries with national healthcare have shown to have better quality of life and longer life expectancy than the US. Why shouldn't we want that ourselves?
