Arguments for government intervention take two paths: political and economic. Political arguments for intervention are concerned with protecting the interests of certain groups within a nation (usually producers), often at the expense of other groups (usually consumers), or with achieving some political objective that lies outside the sphere of economic considerations, e. g., protecting the environment or human rights. Economic arguments are typically concerned with boosting the overall wealth of a nation to the benefit of both producers and consumers.
