Economic protest parties is the right answer. This minor party has its roots in bad economic times, where there was not a clear ideological base. They are not pleased with how the economics is being systematized as well as with its way of course and a change is demanded by them looking forward better times. Some examples are the Greenback Party which appeared in the bad time of agriculture in 1880s or the Populist Party by 1890 which requested the railroads and telephone companies to be public.
