I am against those proposals (except maybe medicare for all). I think we probably have a definitional problem with Open Borders. I don't want Open Borders (and I do not suspect many do), but that doesn't mean I want a wall or draconian measures to discourage asylum seekers. Still, that's getting into the weeds. I tend to agree with you, overall. Would like to cut defense, raise the retirement age a year or two, and figure out a way to rein in medicare costs.
Both of my parents were in the hospital last week. That had to cost a fortune. They needed to be there, though. I just don't know what the answer is.
