The Corruption Perception Index rates nations by corruption. The United States is rated 19 out 177 Countries. Our neighbor Canada is less corrupt, rated at number 9, while Mexico is number 106.
Russia is 127 while the Ukraine and Iran are tied at 144. Most of our G-7 partners are quality ethical countries - part of the reason they are successful.
Iraq is 171 while Afghanistan is 175. So we invaded and tried to modernize these crooked countries into a functioning democracy with a fair and good economic system. Really stupid on our part.
Wringing corruption out of government and society is a challenge. You can't have a quality country with rampant corruption. You top officials simply steal the country blind.
