One of the most valuable assets of a civilization is its dignity.
Dignity Ranking:
1. Western Europe/Wealthy East Asian Countries/Canada
2. United States/Australia/Israel
3. Russia/China
4. South America/Middle East
5. Africa, especially Sub-Saharan Africa, which is at the bottom of the totem pole
Things that may serve to confer dignity:
-A long history of independence
-Material prosperity (most important)
-A fascinating traditional culture and for your country to have been around for a long time
-A strong military/high performance in wars
-A strong democracy and low levels of corruption
-A longstanding peaceful society
Things that may serve to detract from dignity:
-Having long been under subjugation
-Being economically underdeveloped (most important)
-Being a recently born "artificial" country (like, say, the Democratic Republic of the Congo)
-Underperformance in wars
-A weak or nonexistent democracy, and high levels of corruption
-A reputation for violence, civil wars, and coups
When a country has dignity, we human beings are more likely to give a crap whenever something bad happens to its citizens. That is, we actually place a higher value on their lives than we do on the lives of people from countries which lack dignity. This isn't fair, as nobody can help what country they were born into, but that's the way things are and, for all intents and purposes, have always been. Donald Trump said aloud about Haiti what a lot of people have long thought.
When a people lack dignity in the eyes of others, outsiders have lower inhibitions about imposing crap upon them. When a people do not perceive themselves as having dignity, they're less likely to resist when outsiders impose crap upon them. In a country that lacks dignity, the people of said country are less likely to work to maintain what they have. It encourages corrupt leadership.
Dignity in the eyes of others is something that must be worked for. It usually takes a minimum of several decades to build it up. Dignity in one's own eyes is much easier. The likes of Booker T. Washington, W.E. Dubois, the various great thinkers of the Harlem Renaissance, MLK, and Malcom X helped the black community attain this. However, with the exception of MLK (though to be fair people before him laid the groundwork for his success), they failed to attain the long-term dignity of Black Americans in the eyes of outsiders. Blacks initially started out with no dignity, having emerged from centuries of enslavement. The quickest way to gain dignity would've been to become economically well off, but this didn't pan out. With the exception of Booker T. Washington, these various intellectuals failed to put enough emphasis on economic development.
South American republics used redistributive economic policies in part as an assertion of dignity, a declaration that "We have a right to not live in abject poverty and not take crap from rich people". However, as this usually served to erode democracy and prosperity, in the long term they were reducing their own dignity.
Russia has sought to increase its dignity though military might, but they're doing this instead of investing in a modern economy so in the long term they're going to end up quite undignified. Saudi Arabia has used oil to become wealthy and buy instant dignity for itself, but this hasn't translated into a viable modern, post-oil economy so 20-30 years from now they'll likely end up quite undignified also.
China has taken concrete steps to build up its dignity through economic development and a sort of faux pacifism that's lasted for decades, though under communist rule there is probably an upper ceiling as to how much dignity they can have, and in coming years they could erode much of what they've gained.
