Just speculating here but do you think it is because of the strong food culture and links to identity in France?
Tax policy is also very favorable, and public infrastructure usage and pollution costs are not internalized.
Biotechnology, taxation, and regulation would be the answers.
If meat was not heavily subsidised, it would be much, much more expensive.
See how well it turned out for Germany -and the rest of Europe- to transfer it's energy sovereignty to Russia...
Lately, in the supermarket, there would usually be some meat at about 2€/kg, which I could not comprehend, as most other groceries have gone up. Pricewise it's competitive with carrots, potatoes and bananas.
How can meat end up cheaper than ordinary pastry? Measured per kg and yes, meat has a lot of water, but still..
Every vegan/vegetarian food that I try from the likes of McDonalds is surprisingly good and costs about the same as the meat equivalent. In London there is also a fast food chain dedicated to vegan food (Neat Burger), it is fairly cheap for what it is and tastes amazing.
Fake meat has never been so available. There are several restaurants that serve it that are not your "we are explicitly vegan" restaurants, burger king served some, and all major supermarkets have it in stock in the freezers right next to normal meat. However, the price is still unattainable. A few days ago i bought patties to make burgers and meat was about 1 euro/100g and plant meat was about twice as expensive. For as long as it is more expensive, people are going to buy real meat, unless they're trying it (in terms of taste i think it's fine) or vegan.
