The situation is incredibly bad in countless ways for two primary reasons: imperialism and settler colonialism mean that even American workers with shitty jobs are making more money than most people on Earth. That plus more propaganda than any other society in human history means that large numbers of americans believe that socialism is when the government does stuff (and many americans think this is bad). All of this means that it’s difficult enough just to get workers to unionize without even factoring in shitty bosses, the government they control, and the police. And as bad as the situation is, lots of americans have other options—if one job doesn’t work out, they can get another, and that might be easier than unionizing. Americans also hate and distrust one another and view each other (not entirely incorrectly) as lazy evil bastards.

Che says in one of his texts that revolution is impossible as long as large numbers of people believe in the democratic process. As obviously fucked as things are in the USA, many people still believe that the system is legitimate, for all its faults. If and when the american empire collapses and the bourgeoisie starts tightening shit up to shift the exploitation from the global south to america itself, maybe then things will get easier for communists, assuming we don’t all end up carrying anvils and getting gassed in concentration camps.
