Total French private wealth is around $15 trillion (https://en.wikipedia.org/wiki/List_of_countries_by_total_pri... ), French government spending is around $1.8 trillion/year. Even if the French government were to expropriate the entirety of private wealth, it wouldn't even be enough to cover 10 years of spending. Fundamentally the French economy isn't producing enough to support the current level of spending, due to a continuously falling ratio of workers to retirees.

America's $6.75tn budget [1] would blow through our $140tn private wealth in 21 years. Even Norways $0.11tn budget [2] blows through its $1.6tn of private wealth in 14 years.
Perhaps the better metric is deficit as a fraction of private wealth? If that looks unsustainable, the problem is in publicly-held assets and services.
