Let's see -- why it didn't happen here: the two-party system, which requires coalition building before versus after elections. (Although a number of non-socialist third-party candidates have done better than socialist ones, so that doesn't totally explain it) 44.
A trajectory of working people advocating for equality of opportunity versus equality of outcome. American radicals who are suspicious of the state and more sympathetic to libertarianism and syndicalism than state collectivism. Co-ops, communes, and collectives should be the place to try radical futures. A history of US lacking both feudal and peasant classes, so that all conflict occurred among various levels of the bourgeoisie. The fact that everyone's incomes have been rising, although comparative inequality didn't change.
"Even today (2000), "distribution of wealth has grown more unequal, but consumption and the overall standard of living have not. In absolute terms, the less privileged are better off than before" (28).
America as a country is an idea, not an organic pre-existing thing -- it's an ideology versus a place. And that ideology tents to include: anti-statism, laissez-faire, individualism, populism, and egalitarianism. (29)
Socialists have been separate from the working class parties in the US -- socialism was treated as a dogmatic/ideological thing versus a practical solution for working people.
Lack of a history of repression -- working people have long had the vote, and "political freedom undermines class consciousness" (34-5).
The ability for Americans to become landowners as an alternative to wage labor in the event of expropriation of Indian lands led to a nation that saw themselves as independent landowners versus wage laborers (58).
US tradition of craft versus industrial unions -- led highly skilled workers to fight to preserve their "niche in the division of labor rather than to abolish the division of labor itself" (88).
Unions themselves (i.e., Gompers) "oppposed government old age pensions, health insurance, minimum wages, unemployment, and legislated maximum hours laws" -- they saw the government as more difficult to fight than the corporations.
the New Deal was the first example of a class vote, the first support for state backing of lower unemployment & assistance to citizens.
immigration created ethnic diversity that cut across/fragmented class identities (125)
because socialism was split from the unions, it became very ideological and radical versus reformist (114).
There were two chances to establish a socialist party -- 1912-1920 and during the Depression. Teh tension between radical social movements and reformist political inclusion ended up on the siden of political inclusion (237).
