So livable that people are no longer having children? So livable, that people no longer see any hope or meaning in their lives and the future?

The highest incomes on the planet, are in monarchies like Liechtenstein and Monaco. Singapore, which cannot be called a democracy, is one of the safest countries on the planet.

Another interesting way to look at it is at the debt. The debt of most (all?) democracies is sky rocketing. That means the "livability" is an illusion paid for by borrowed money.
