Printing more money cannot make everyone rich. Why?

I am writing this post since most of us are interested in money. When I was in 7th grade, I had this huge doubt. If it is government’s job to print money, then why can’t it print more money and give it to people to solve all the problems. I even believed, government is too lazy to print and distribute more currency notes :) . I asked this doubt to my parents and teachers. But at that time, I was unable to get it clearly. Years later, when I surfed internet, I have seen, it is very common question for many people. So I referred few sites and got some understanding. By the way I am sharing it with you .
