The libertarian platform has included all the following causes except:
a.
limited federal government
b.
neutrality on foreign affairs
c.
regulation of business
d.
strong civil liberties

C. Regulation of business

In overall, the Libertarian platform promotes a classical liberal platform, which means that it strongly advocates for civil liberties under the Constitution, and it puts an emphasis on economic freedom. It also aims to limit the federal government and to promote a neutrality policy on foreign affairs (it intends to avoid any foreign entanglement while enhancing the likelihood of peace while emphasizing defense against attack from abroad).

As a promoter of laissez-faire capitalism, the Libertarians oppose any type of government regulation or intervention on business (collection of taxes, subsidies, and bailouts to business,etc.). They favor free-market banking, with unrestricted competition among banks and depository institutions of all types, and they favor free markets as well and opposes that the government competes with private enterprise.
