Be a Millionaire Day is observed on May 20, 2017. The day can be celebrated by anyone who is not yet a millionaire. A millionaire is an individual whose net worth or wealth is equal to or exceeds one million units of currency. It can also be a person who owns one million units of currency in a bank account or savings account.
While millionaires constitute only a small percentage of the population, they hold substantial control over economic resources with the most powerful and prominent individuals usually ranking among them. Also, the total amount of money held by millionaires can equal the same amount of money held by a far higher number of poor people. (With material from: WIkipedia)
