Final answer:
A person who disagreed with the Wagner Act would most likely support the creation of the National Labor Relations Board (NLRB) to protect workers' right to unionize and bargain collectively with employers.
Step-by-step explanation:
A person who disagreed with the Wagner Act would most likely support the creation of the National Labor Relations Board (NLRB), as the Wagner Act created the NLRB to protect the right of workers to unionize and bargain collectively with employers. The NLRB would enforce the provisions of the Wagner Act and mediate disputes between unions and employers.
On the other hand, someone who disagreed with the Wagner Act may not support the creation of the Social Security Act, Francis Townsend's old age revolving pension plans, or welfare capitalism programs put forth by business leaders, as these were separate initiatives aimed at providing social welfare benefits and assistance to individuals, rather than focusing on labor relations.
