Why spend so much money on making records?

On December 16, 2013 Bangladesh made world's largest human flag in which 27117 people took part. Then on March 26, 2014 Bangladesh made another world record: 2.5 lakh people sang the national anthem together. We   spent a large amount of money for organising these two events. We heard, more than 50 crore taka has been spent for singing the national anthem.
But do we really need to make records of this sort? National anthem is in the hearts of 16 crore people. The sons of this soil sacrificed their lives for their mother tongue, and February 21 is observed throughout the world as 'The International Mother Language Day'. Then comes our Liberation War; only in nine months our freedom fighters were able to free the country from the occupation of Pakistan and gave us a sovereign country.
Other records are insignificant to the above mentioned feats. So why spend so much money which could have been used for other purposes?
