Why people always concerned about money?

In a realistic sense, yes money is everything. Even though it isn't absolutely necessary to live a decent life, 90% of the world would agree that being without money is damn near a death-sentence. The other 10% probably live of the land or don't own anything anyway.

Because they don't have a steady flow of income. Most people have income coming from just one place. I have a couple of businesses along with some articles on Hubpages. I make a few hundred dollars a year at least from it and I haven't done much over the past couple years. Sign up and see if it is something you are interested in.

Because money is power, power is choice, and choice is control.

People just want to control their lives, so they seek after money to give them the illusion of grandeur and meaning in life through thrill-seeking or doing things that they wouldn't have been able to do if they had been poor.

That is why people seek money, they think that it will fix their life.

No, money is not the most important thing. I have known very wealthy people who were not very happy, and I have known people with very little who enjoyed life. I am not saying money isnt important, because it is. What I am saying is that a person's perception of the world and their attitude about it is more important to happiness than money.
