Final answer:
The statement is true; the Taft-Hartley Act of 1947, which restricted union powers and was passed over President Truman's veto, symbolized the post-WW2 debate over government's role in society and had lasting impacts on union membership and organization.
Step-by-step explanation:
The statement that after World War 2, US residents and Congress battled the role of government in society, and that the Taft-Hartley Act symbolized this fight is true. After the war, debates on government's involvement in economic and social issues intensified. The Taft-Hartley Act was a centerpiece of this struggle when it was enacted over President Truman's veto in 1947. This legislation significantly curtailed the power of labor unions. Key features of the act included banning closed shops and requiring union leaders to disavow communist affiliations. It allowed states to pass 'right-to-work' laws and gave the president the authority to delay strikes that could impact the national economy. Consequently, this act led to a decrease in union memberships and had lasting effects on the organizing capacity of unions, particularly in the South and in emerging technological sectors.
