I pay out of pocket from my paycheck into my health care. Why are some people against universal healthcare. If its going to affect me and my family negatively, Im going to be against it too. What are your thoughts?

I already have health insurance. I have “Cover Florida Plan II” through Blue Cross Blue Shield. Will I just keep paying for my insurance like nothing happened? I am happy with my insurance and I don’t plan on changing it, unless I have to for some reason.
