My only reason, to impress other people.
There are only three things that receives loved unconditionally, one is women, second is children and the last one is dogs. I, as a man, must have everything especially money in order to be loved.
Even I don't really like to sacrifice everything to make money, but as a man, I'm forced to do that.
I've sacrificed my time, my happiness, my energy, my friends, my moral, etc just to earn as much as possible.
Well, everyone has a reason to earn their own money, otherwise, I don't see why I'd make money only to impress others. When you try to oppress other people because you are making money, they will discover that you are making money and will come to you with their financial issues. You showed them that you had money. For me, living a quiet life and earning your own money is the best that a guy can hope for, I don't see the point of earning money and leaving an expensive life for others to notice improvements in my life. It's okay as long as I'm using the money to make my family happy.
Naturally, having money is a must for men. Many of us lose many people we care about because we have given up everything for the sake of earning money, and we are forced to do so because no one else is meant to earn money for us unless we give up other things in order to focus our time and energy to earn it.
