How does sustainable development endure high standard of living and increase in productivity?

Can someone also please explain how sustainable development makes sure that the objectives of removal of poverty, inequality and illiteracy are achieved?

I think sustainable development enduring high standard of living and increase productivity easily apply and feasible to rich resources country, like Canada. For instance, they can log the whole mountain of woods and replant it. Many years later, the whole mountain goes green again. Salmon hacting by manual spawning can increase its productivity is common in Canada. They grow wheats and mustard a lot there, too. People can buy cheaper draft beer and more hotdogs go with mustard. In contrary, Hong Kong is not a viable city to provide sustainable development for its six million plus citizens because it’s not a natural resources base city, and government personnel has taken too much money out of the system and spend lavishingly too much for themselves. I think a city or country must have good leaders to provide sustainable development endure high standard of living and increase productivity. Hong Kong is just a city become the people don’t give a damn to each other. The inflation goes up rapidly and the government just by selling the lands at extra high prices and investing the monies into the foreign currency exchanges and stock markets. Hong Kong is notoriously known as top five most expensive and polluted city in this world. Hong Kong has the highest poor and rich gap in this world with gini coefficient of 0.5333 and 0.3 is the norm. How to remove the poverty in Hong Kong, for instance, Hong Kong government should cut the overpaid civil servants salaries, lower the property values, keep the Heng Seng index down to less than 10000 point. Then Hong Kong will become a cheaper city to live. Educational subsidary has provided free education up to grade 9 now.
