Is it? I don't know what the National Front stands for in economics
In short, and quoting from an article in March (so maybe some more precisions are missing):
- Getting out of the Euro, re-establishing national currency and a national bank.
- France would then borrow money at no interest to French Central Bank to reduce debt to 50% of current level by 2025.
- Lifting minimal wage, paid for through a 3% tax on all importations.
- Freezing oil prices of reducing the VAT tax on it to decrease it.
- A special subsidy for parents once they have two childs or more.
As expected their economic policy ties in with their political ideologies: Exiting UE to regain control at the national level on all matters, protectionism, pandering to the worker classes hugely dependent on their car, favoring natalism. Probably some Vichy France undertones here, I would expect ("work, family and fatherland").
And of course, even if unsaid, you can pretty much expect that their unemployement policy is to get "illegals" and "foreigners" "stealing jobs" out of the country. That was one of the famous posters of the party one or two decades back.
Beware though that in France, a centralized strong state is part of the tradition, even on the right (although the gaullist tradition has pretty much faded away as of today). I am saying this because too often, presence of the state at the economic level is equated with "leftism".
