1) Mandatory physical fitness program for all citizens. Lame, crippled, lazy, fat, or physically deformed are to be executed. Physical fitness examinations to be taken every year.
2) Education must be high priority. Mental evaluations to be conducted on a semi-annual basis. Those who pass are given a "Procreation Card" and permitted to spread their genetics after 18 years of age. Those who fail are separated from the populace, sterilized and given decent wages for undesirable occupations such as plumber or sanitation engineer.
3) Disease must be eradicated through vaccine or exposure followed by extensive treatment. Incurable or terminal disease carriers are separated to an isolated island or... continent... (ahem, Australia; Hey... it's big enough and out of the way enough that's all, I DO like Aussies). At this mass facility disease will be constantly under study and surveillance. Any cases deemed "Officially Incurable" are to be incinerated to halt potential spread.
4) A military force must be maintained. Elite training required for ALL military personnel. No longer will there be a dividing line in physical requirements based upon military branch. Specific training will be continued to a degree though; Army doesn't really need to know how to moor an Aircraft Carrier, and Sailors don't really need training in digging fox holes or setting up land-based perimeters. Constant training and progressive improvement even in times of peace to act as a deterrent for malicious action or unrest, not as a peace-keeping force. THE MILITARY IS NOT A POLICE FORCE! Civilian police will be trained for that purpose.
So, in my world we have health covered, both mentally and physically, mandatory education and a powerful fighting force if need be.
All that's left is money, food for all the mouths and clean living conditions... Hmmm, difficult...
I quit.
