Word “Middile class” is the class which upper class for lower class and lower class for upper class. It is the class which have both lower and upper medium. But the question is middle class people are happy fir being middle class people? The answer is simply ” those people are happy which happy with their life and happy with what they have” those people who stuck their happiness with those things they haven’t have are always blame himself and their family and their life and not happy at all. It is good to have big dreams and it is even better to work hard to fulfill them, but if you don’t wanna do hard work and still want your dream come true then its unfair to your self and your life because in this way you will always blaming other for your failure. And the middle class is the one which i talked about. Because upper class already lives in their dream life, lower class survives for their food and shelter, they want from their life is just 2 time food and and a place where they live with peacefully and middle class have food and shelter but they want their dreams come true. Do hard work for your dreams and not stuck in your failure.
