Could you please clarify the healthcare system in France for me? I've heard rumors that it's free, but I'm not entirely sure. Do French citizens enjoy completely free healthcare, or are there any costs involved? Are there any specific services that might require additional payments? I'm particularly interested in understanding how the system works for those who are not employed or who might have low incomes. Could you also explain how foreigners residing in France might access healthcare? Your insights would be greatly appreciated.
