High end audio and diamonds have something in common
Diamonds used to be worth money since they could be used to cut hard materials. Eventually, humans figured out how to manufacture diamonds flawlessly so "natural" diamonds basically became worthless. Why pay more to get less?
So what do you do when faced with the fact you are mining useless rock? Advertise and create demand from the ignorant and make it fashion for the masses! Never mind that the diamond market gets many of them from counties in Africa that have the habit of killing people for them to fund their chaos. We can certify a rock to not be from that area...cuz everyone knows diamonds have different flavors depending on where they were found. Perfect!
The strongest armies are the richest? If that was true the Roman Empire would still exist or at least, the British Empire would control the world. The strongest armies are the ones that believe in what they are doing, will stick to the final result and never stop. An outstanding example of that is Castro and his rebels overthrew the Cuban government although they were outnumbered and poorly equipped. Another example is ISIS, they blew away the much, much richer Iraqi Army and overran the area quickly. However, they have now run into the Kurds which have an even stronger purpose but less weapons/people/firepower...and the Kurds are pushing them back. When it comes to that, no amount of money on the planet can stop a force that is willing to die for what they believe in.
After all, money is worthless...the only reason people think it has a value is because....they think it has a value. This explains how speaker wire can be "worth" $5,000 a meter. In reality, if you can't eat it, drink it, breath it or be protected from predators or the elements...it is worthless.
