The leaders where determined and developed their own country with their personal mineral resources mostly gold and crude oil, they saw a vision and they worked towards it ,it become possible when they saw the need too .
Many of undeveloped countries are probably battling with cirrupt leaders, who are concerned about their personal interest and how to embezzle funds and convert it to theirs.
If only this countries can adupt china policy for death by hanging if found guilty in corruption then it will put those leaders in their right senses.
Dubai emirates raised from grass to grace and even did it better than most developed world leading countries because they valued themselves and had taste for greatness.
No, they did not rise because they valued themselves and had taste for grateness, they have black oil. Period. Dubai is a perfect example of what bad city planing and flashy over the top vanity projects can become when you are new money. Corruption has nothing to do with it, and it's easy to have a vision when you have the means to do it, unlike many other underdevelooed countries. So Dubay is good examole of nothing at all and applicable to nothing.
Oh and I forget, they rely on capitalist slave labor from porer countries. Great role models.
Capitalist system sure beats what happen with Venezuela. Their currency used to be one of the most valued currencies in the world supported by all the oil they were producing. Problem was, they elected a socialist that taxed high income earners and poured money into welfare programs ie wealth redistribution. Then oil prices crashed and they couldn't sustain their economy anymore. You need more than just oil to create a successful economy. It apparently takes some effort not to crash the country into an economic ditch if Venezuela is any indication.
