After the great depression in 1920s, the "Roosevelt New Deal", a major American political and economic restructuring, is behind the starting from the end of the nineteenth Century, the bottom-up development of the "progressive movement by thirty years"
(Progressive Movement); in twentieth Century 50s and 60s, the United States has made significant progress in the political aspects of racial equality, the fundamental force comes from the racial equality of social movements raging like a storm; and in twentieth Century 80s, U.S. economic policy is in Reagan's comprehensive administrative right period, one of the most important factors behind, 1970s is the beginning of a series of conservative social movement and these movements tend to commercial capital&nbsp;or&nbsp;the middle class as the main body, a plurality of social groups for the "high tax, high welfare, the pro labour" economic policy framework of discontent fully mobilized, California's "tax revolt" is one of the typical representative.
In the history of the United States, only the mobilization ability strong, built on the basis of social sports development on political power, in order to successfully grasp the political opportunity to reverse the political agenda. But where is the foundation of the social movement of left-wing political forces?
After 1980s, the manufacturing unions based on stable employment mode, at an alarming rate of decline, the new mode of labor mobilization has not formed; almost from the same period, the Left-wing Movement issues become more and more diversified, Racial Equality Movement, women's rights movement, sexual rights movement, the environmental movement, anti war the movement and fight the enemy separately consistent action is almost non-existent, and greatly weakened the mobilization of the basis of these movements
Occupy Wall Street in 2011"
(Occupy Wall Street) sports spectacular, but after months of exercise ended, leaving the social movement organization heritage is very limited, can not form a continuous, rooted in the community mobilization momentum --- the 2010 outbreak of the right-wing grassroots conservative "Tea Party movement" (Tea Party Movement), foster efficient, master a large number of resources sports organization network, making the "Tea Party movement" of the political agenda can continue to influence the political pattern of local and national level. In contrast, the ability to mobilize the left-wing organization is weak.
In the mobilization and organization ability so scarce social movement situation is relatively weak foundation, more political opportunity, the significance of the development of left-wing political forces. There should be more to the public. Chairman Mao said: the people, the masses are the main force of social progress. Why did Che Guevara fail? Because, confined to their own not only the liberation of the liberation of their own, but his own, like a drop of water into the sea of people.
