I feel like you've never visited any rural area. I grew up in a rural area and most of the people I know from growing up ended up in a city at some point in their life because of the lack of opportunities in the rural area, but very few people fit the stereotype you're putting forth. The place I grew up was a farm town, and my family were also farmers, everybody in my family went to college even though we weren't well-off, and that's true for most other farm families. Farming these days is actually strongly technology-focused, and people go specifically to college for agricultural studies to learn how to cost effectively and sustainably operate their farms. I'm the odd one out in my extended family because I moved far away and went into the tech industry.

I would strongly challenge your belief that rural people are uneducated and unintelligent, it's mostly the exact opposite. Many of the rural people have skills and knowledge far beyond what the average person in the city does, because they have to do more things for themselves in their day to day life. City life is mostly about specialization and formalized/structured job roles and living. Rural life is about doing whatever is necessary to succeed and moving things forward one more day. The average farmer has a strong understanding of multiple trade skills (plumbing, hydraulics, welding, mechanics), as well as at least a basic understanding of mechanical & civil engineering, at least a basic understanding of biology, and at least a basic understanding of electrical systems.

The only thing you really get right here is about the economics of the situation. Rural areas experience brain drain and are shrinking over generations, part of that is due to increase mechanization and automation in farming which reduces the need for farm labor and creates drive for the children of farmers to go into other fields. The lack of employment and economic opportunity is real, and it is something to give due consideration before deciding to move to a rural area. But it's not because people there are stupid, uneducated, or whatever stereotype that comes to mind.

And, on the note of politics, most rural people are more Libertarian than Conservative. They frankly don't care what you do as long as you leave them alone and stay off their land unless you're invited. In my life I've had FAR FAR more negative interactions with other people trying to enforce their beliefs on me in the city than I ever have growing up in a rural area, and at this point in my life I have roughly 20 years of experience in both situations. A basic, simple, and common example is how HOAs operate vs how local politics works in rural areas. I would not describe rural people as Conservative, and I don't know how you'd want to politically describe most city people (Liberal seems inaccurate), but city people are generally busybodies and expect everyone to conform, rural folks don't care what happens on someone else's property.
