Why don't people do things the way the Spartans did?

Well, organising a city for a permanent state of readiness for invasion was quite a feat on the Spartans' side. BUT, the popular report doesn't generally include the Helots. The Helots were the slaves (they were the local populace, the nobles and free men being invaders), every year, in order to stop them rebelling against the iron fisted rule of the Spartans, the Ephors (9 elders) would declare war on the Helots. Helots were treated worse than the dirt on the sole of your shoe, would you want to be one? Also, the children had to go through the agoge, or training, a sort of tough love initiation into the Spartan world. Children were gathered together into 'packs' and left to fend for themselves. They were given no clothes until the age of 15, when they were allowed a cloak, nothing more. They had to sleep outside in the freezing cold, even in winter, and made blankets out of moss and leaves. They were so cold, children puit thorns into their blankets to make them have the illusion of warmth as they were stung and pricked in their sleep. Would you honestly like to do that?

I severly doubt that in this day and age of human rights etc that a Spartan society would not be annexed from the rest of the world and invaded. Not a very good plan...
