It makes sense, actually. If you have a plot of farmland and you work it, you know where your next meal is coming from. For the most part, if you control your means of production, you can be sure your efforts will be rewarded. In a condition like that, the Republican claim that people suffer from hunger only because they are not willing to put forth an effort makes sense.
In the city, there is a different dynamic. Workers don’t have a resource that, if they put the effort in, they will reap rewards. They have to rely on jobs controlled by an elite group of people that are actually adverse to their interests. They know that you can work hard looking for a job, not find one, and still have no paycheck. They know that you can be loyal to a company for 20 years and get a pink slip for no obvious reason.
Some people seem to think that poor people voting for Republicans are voting against their own interests. As long as these people are under the impression that their work will be rewarded with their next meal, that is simply not true. If they have no reason to think their efforts will be futile (or, indeed, if they won’t be futile) the Republicans are not against their interests. It’s when someone else controls whether you will be allowed to eat that there is a problem.
