Ok so what is nullifing the existence of class struggle and class itself in the United States?
Nothing nullifies class struggle. It exists everywhere in the modern world and at anytime.
You can't just say that when you have also said this;"No, we don't. Quite to the contrary, what passes for the left in the United States is primarily content with the status quo - which is a proletariat blissfully ill-equipped for class struggle. This country is so far from class consciousness and a worker's movement that it would bring a tear to any Fascist's eye. "
You both admit and deny that Class struggle is happening , that it is and isn't nullified. I get the impression that you are very well read , but you havent reconciled all of your learnings with each other.
Americans do not recognise class , I am a Mister and so are you , if you work really hard you might get an honorific like Doctor or Senator but not an American Lordship or Peerage nor can you become a higher caste even if you become very pious in your religion , I cannot be required to pull my forelock in deferance to you nor you me , we may honor each other willingly , perhaps to acnoledge learning or accomplishment , but even that is an option of manners not a fact of law.
I feel a brotherhood with Benjamin Franklin thjough I don't feel I am his scientific equal , I feel a kinship with Thomas Jefferson though I have a fraction of his energy or genius, these guys wanted a brotherhood of Americans and they eschewed the peerage that they were well placed to erect preferring to adress their brother Americans as equals even tho they had entirely the option to establish a seaprate caste for themselves.
This is the country where you claim to have been born in a log cabin if you want to be the top boss if you were raised by the uppercrust that is a problem to overcome , even some wellborn claim humility in order to get chosen the class struggle isn't real here.
