A leader gets double the dirt to build on if he's the most excellent and most skilled of all the leaders. You don't think dirt is so great? Well what if I took the dirt you own away from you? Your house is on that dirt. It's mine now. Get outta here.

This excellent leader is going to use all this dirt to store her excellent cars (か)! Excellent people have to have cars in equal or greater than excellent-ness than themselves.
