I highly recommend reading "Guide to the Perfect Latin American Idiot" which explain how dictatorships can pick a handful of indicators and elevate them to first-world levels while still making everybody's life miserable.
The indicators per se are not gamed. Instead, you select a few indicators like "Olympic medals", "life expectancy" (etc) and commit every resource of the country to them at all cost and without regard for everything else. The indicators you picked will show amazing and you can use them to justify your ideology. Pretty much like a SEO hack, they are hacking public opinion (looks like it worked on you).
