It would be a lot cheaper than if she subsidises by the state every single company in France that goes bankrupt , on top of which adds 3% to all imports, adds 35% to all imports from French companies that move their production abroad, build 40000 more prison places, employ 15000 more police officers plus shut all the borders and thus employ thousands more border personnel, customs officials, never mind the civil servants for the VAT duties and so on. Then change back to the franc , reduce retirement age , limit immigration to 10000 per year and tons of other nonsensical economic disasters. She hasn't said how she's going to fund any of this.
Reminds me of the nonsense that the Brexit crew came up with, just waiting for the bus now, hopefully we only have another 10 days of this rubbish
