Life is always going to be difficult on earth. If everyone has a fixed salary then no one would have worked and this way leads to food scarcity. If peoples start to open a hotel and other daily need product shops with their hard work they'll become rich day by day and in this way everybody will not be equal. If you start to work for your family then in this way it leads to the day that we are living now. So in my opinions everyone couldn't be equal at all time. Their has to be ups and downs in life to maintain equality. Thanks @ionutciobanu. Good night friend..
