Diversity brings lots of benefits , whether it's at the national level or the individual level. Many individuals argue that diverse cultures with different skilled workers and professionals, from different communities and beliefs, bring with them various advantages. I firmly agree with this notion because it is evident from various developed countries that a strong reason behind their progress is the availability of mixed expertise. I will discuss both the merits and demerits of mixed cultures for any country's development, and then conclude with my opinion.
