What is considered rich in France?

Could you please explain to me, in English, what the definition of being wealthy is in France? It seems that standards of affluence can vary widely from country to country, and I'm curious to know how France compares. Could you outline what sort of income, assets, or lifestyle would typically be considered wealthy in France? Also, are there any cultural or social factors that influence this perception? Thank you for your insight into this intriguing topic.
