AZ you know very well that the term 'far-right' is not applied in general discussions on the economy or in fiscal terms. 'Far right' parties refers almost exclusively to their social policies. France's National Rally, Italy's Brothers of Italy or any other party labelled far-right will not be on the extreme liberal wing of economic theory - more likely the opposite.
If you looked at a party like the BNP, their economic policies are all about market intervention, giving workers stakes in the businesses, rhetoric against bankers etc. That stuff would typically be considered left-wing.
The left-right scale just doesn't really fit comfortably on the economic spectrum.
