Almost everyone would agree that government regulation of some things is absolutely necessary, while people of varying political views disagree about what things and how much. It seems to me that more government regulation of the securities industry would be highly desirable, including the manner in which financial products are promoted and sold to the public.
Of course, the rising popularity of the internet and the increasing access to information it makes possible goes a long way toward exposing and preventing abuses. Scams and frauds that have been rampant in the past will eventually become more widely recognized.
Such issues are highly relevant to financial planning. To regard them as "off topic" just restricts what is considered to be "on topic" to views that everybody agrees upon and which therefore are bland and have less practical importance for newbies and people trying to learn more.
