From Mr Jeff Erber.

Sir, Barney Frank’s assertion that “America’s 30-year experiment with radical economic deregulation” has resulted in the widest income inequality since the 1920s and a collapsed mortgage market is wholly untrue (“Why America needs a little less laisser faire”, January 14). His proposed “solution” is itself flawed and contrary to the principles on which the US was founded and that have led to its vast economic success.
