Reality or Myth...?

Is The American dream a reality or a myth?
For years people have been coming from any country of the world to The United States, and only one reason brings them. What is it...?
Someone once asked me: Would you like to sweep up dollars?
Obviously my answer was yes, how would I do it ?, I asked. For a moment I tought this guy was crazy. Then he told me just to walk north, and that on the other side of the border I would find a lot of money easily, but he never mentioned the cost of this. My friend heard this conversation and tought it was an excellent opportunity. I had little money saved, and he had nothing, even so we decided to do it. The next morning we boarded a bus and after 32 hours we reached the border. We ate there and bought water, after that we hired a "Coyote", he told us it would be easy to cross the desert, he lied to us. Crossing the desert is like putting a gun to your head with one bullet, temperatures there are deadly. I carried in my backpack some candy, beef jerky, paper and a pencil. We walked for 12 hours and the heat was terrible, we only carried 3 gallons of water, these were finished after 6 hours. The thirst was killing me and I started to hallucinate, I felt that the end was near. I asked them to give me a few minutes to write this letter and they agreed to it. If you are reading this letter, you will understand that these were my last words, and that means that my friend survived. I died, and never knew if The American Dream was reality or myth. What is your experience?
Was it true what that man told me?
Could you sweep up dollars?
