Final answer:
J. Pierpont Morgan did not specifically say he would 'tear down' any particular businesses, but he was involved in anti-trust suits to regulate big business.
Step-by-step explanation:
In his efforts to reform and regulate big business, J. Pierpont Morgan did not specifically say he would 'tear down' any particular businesses. However, Morgan was involved in several anti-trust suits, including one against the Northern Securities Trust Company which included powerful businessmen like John D. Rockefeller and J. P. Morgan. The suit led to the breaking up of the trust and demonstrated Morgan's role in challenging and regulating big business.
