I believe the parent commenter was noting that with universal healthcare the relation to poverty and not being to see the doctor was not longer a problem.
Here in the UK I didn’t think house calls exist, but then my wife got a severe chest infection while she was pregnant on a weekend. I called the NHS help line, and there was a doctor with us in 4 hours.
My Dad was a doctor, so technically we got a house call everyday. But the reality was that we never saw a doctor at all. If we needed a physical for school sports my dad would just look at us and say "Eh, you look healthy" and sign it. I was in my early 30s before I got a real checkup from a doctor for the first time since I was born.
Actually, yes. Also, whenever one of us needed a medication he would just write the prescription for what we needed. The only exceptions were if one of us broke a limb. Then he'd take us to a friend doctor who specialized in that sort of thing to fix us up.
When I was kid in Germany the doctor would do housecalls when I had fever. These days I can imagine this done only for very old people, either in Germany or the US.
