Is having a lot of billionaires something to be proud of? All it shows is the wealth/income inequality in your country... Generally a sign of a poorer economy. The ideal situation is to have a large middle class, with small amounts of very rich and poor. In India it is the opposite, you have a small middle class with a lot of millionaires and billionaires and hundreds of millions of poor people.
Also you gave some examples of monuments for Khojali massacre (regrettable event it was). Let me give you just some of the monuments for Armenian genocide;
Cardiff, Wales
Marseille, France
Valencia, Spain
Esfahan, Iran
Arizona, US
California, US
Der Zor, Syria
Antelias, Lebanon
Beunos Aires, Argentina
Nicosia, Cyprus
Montreal, Canada
Assen, Netherlands
And many many more. So don't think that the international community has forgotten about Armenia...
