I'm 80 years old and the first generation of my family to grow up suburban. Which is to say, dependent on city amenities. My family pushed me and my cousins to get a college degree. And nationally, we are legion.
The rural people you write about are my people. I spend time with small town/rural people often. In many ways I feel more affinity with them than suburban/city folks.
The Democrats talk a good game, but you're right. If "we" don't pay attention to and support the real lives of this "other" culture, we're all screwed.
