Exactly. The problem is access. It's very unequal in America. if you can get it, it's amazing. 15% of Americans cant't.
Massachusetts or Denmark is a great counter-example to America as a whole. THis is the state of Massachusetts.
Massachusetts is 10,500 square miles (Denmark is 16,000). It has one major city (Boston, in the east) and two minor cities (Worcester, in the middle of the state and Springfield). If I live in Springfield and get sick, I can easily drive to Boston on 90 west. It's about 90 minutes away. This gives me tremendous access to world leading Healthcare, that my insurance will cover, because that's what State law requires. To treat all of Massachusetts, we need world leading hospitals in one hub, for all 6.7 million residents within 10,500 square miles.
Now let's look at Texas.
268,597 square miles. Twenty five times that of Massachusetts. Population of 27 million. That means it's far less dense and just looking at the map you can see that people have to travel far greater distances to get to major cities, and those cities have and uneven quality of healthcare providers. Massachusetts gets by with one hub because it's a 90 minute drive between the most distant densely population regions. Texas needs more than it has for 7-10 hour drives. Way more.
In a sense it's kind of like internet. Many American cities have really, really good internet. Mine in Massachusetts is Comcast cable at 180 Mb/s down. I can get fiber if I wanted to. How much better is many Europeans? Can you beat 180 Mb/s down for cable? But I live in a rich, densely packed region. People two hours north in the woods. will be lucky to get 10 Mb/s.
Scale and inequities is the heart of the problem. Both are fixable through better policy and efficiencies. But neither are trivial.
