The spirit of any nation-- lies with the motherland; as the erection of society lies with the structure. Now, to have many different races occupying the same country-- is a tricky-subject. On one hand, in a city like New Orleans-- it's predominately African-American. In the turn of the 18th century, Creoles ran things-- much like the Indians, are all but extinct.
Roadways and Highways, are not being managed properly; as it will take a coordinated effort from, local, state, and federal governments. Think of the roads as a track, and all the cars and trucks as interlink-- muck like a train. When drivers ignore the posted-signs, and start speeding/tailgating -- it throws off the flow-of-traffic, which causes accidents.
