Down of Zchi Civilization

Wanted to tell an interesting story that simulate my situation / thinking.

Once upon a time in a far away galaxy called Neurobian Galaxy, lies a planet called Gimba. This planet houses a lot of separate clan, ranging from :
1) Goak (the higher society order) -population ratio : 40%
2) Zchi (the middle society order) - population ratio : 15%
3) Tenbo (the lower society order) - population ratio : 20%
4) Others - population ratio : 25%

Couple of years back, A fraction of Goak clan themself started a war against the people of Gimba and lost. The rest of the clans went into a dark age and Zchi emerged to be the economic expert, controlling most of the financial and foreign exchange. Goak clan controls most part of Gimba and have established themselves as the standard for the world. Tenbo clan struggle to survive in a fast pacing environment due to the inflation and economic pressure set by Goak and Zchi clan.

There's this country at Gimba, it's called Alysiam. Population was consisted of 70% Tenbo, 25% Zchi and others 5%. The country of Alysiam is politically controlled by Tenbo as they are the main voice of the senate, they virtually placed all benefit to the Tenbo population, reducing Zchi's privilleges on lifestyle and placed themselves on a different standard than the Goak people. Because of this, as world inflation rise, the impact was felt TWICE on Alysiam because of the exchange different.
The administration of the country was also severely hampered by the biasing of Tenbo towards their own population, they voided the Zchi of business monopoly, enacted high taxes scheme for non-Tenbo and encourage Tenbo's population to bloom with great sports facility, superb educational facility, great career oppurtunity and hugh benefits in acquiring assets and properties, while doing the opposite for the remaining non-Tenbo race.

This is not the problem, the biggest problem is, the population of Zchi residing in Alysiam is pretty much contended with themselves, believe everything the zionist Tenbo clan said and live a peaceful life. The only complain that will ever come from them is when the road leading to their work place is too bumpy or when the government choose not to give them a public holiday when one of the Zchi ethnic won a great event.

If one could see that far, one will notice that the Zchi people can actually do so much, but they choose to do so little. No doubt one day this clan will be assimilated by the majority of Tenbo group, but it's sad to see the great population of Zchi would have to face such fate, given the great history established behind...

They say great civilization will always be remembered, like the ancient Babylon, the people of Troy, Roman empire, but none will remember the minor civilization of Zchi living in Alysiam except for the help rendered to the independence of Alysiam from the Goak which would probably be forgotten anyway since the Tenbo people would remove it from the historical book. Sad but true.
