By the way, since 5% is the optimal dividende for an 80 years life expectancy we can estimate what should be the universal dividend in monetary zones.

There are 15 000 billion US dollars in M3 more or less (see M3 shadow stats) for 303 millions of citizens.

So the Dividend whould be in 2010 of : 15 000 / 0,303 * 5% / 12 = 206 dollars / month / citizen

In EuroZone we have M3 = 10 000 billion euros in circulation and 322 million of citizens.

So the Dividend whould be in 2010 of : 10 000 / 0,322 * 5% / 12 = 130 euros / month / citizen

With great differences into the zone : Minimum social in France is around 500 euros / month / citizen, like in Germany, and minimum legal work income is around 250 euros / month in EuroZone countries such Slovaquia and Hongria (which is not legal is France and Germany where minimum work income is around 1200 euros / month).
