These people have real and legitimate grievances. Their government has failed them.
Yes, they do and yes, they think it has. The problem is that they have been in the business of voting for people who campaign on the “Government is bad, vote for us and we’ll show you just how bad we can make it.” It’s their own fucking fault that the government doesn’t work as well as it could. And despite their best efforts we still manage to have rural internet to connect them to the world in places where they would never be able to afford it, interstate roads to send their crops to market and bring every modern amenity to their local stores, a national air transport system to bring them a new liver or kidney after they’ve destroyed theirs, working ports to bring their tractors and 4 wheelers and snowmobiles, billions upon billions of dollars in (otherwise unaffordable) crop insurance and price supports for their products, and an army of adjusters with stacks of cash to rebuild after every tornado, flood, heatwave, snowstorm, hurricane, and forest fire.
The government has not failed them, they have failed their government. Their hand is out whenever they have a bad day, but their memory is wiped out every time they see that all those benefits might cost money.
