From the 1950's to the 1980''s profits earned by financial firms excluding insurance and real estate accounted for 10% of total US profits. This grew to 22% by the 1990's and jumped to 34% from 2001 to 2005. A financial sector of this size becomes a danger for the US economy, especially with overleveraging, high-frequency trading, excessive risk-taking and other practices common before the crisis of 2008. It also does not add to the productive strength of the US economy, and diverts human and capital resources that can be productively used elsewhere in the US economy. A large sector also creates its own self-perpetuation mechanisms such as efforts to dilute or reduce the regulation needed for it to function safely and productively. By diminishing the power of the legislative and executive branches of the US government to regulate this sector, it also reduces public confidence in government.
