If you were given 1 dollar for every second since the day you were born, you would be a millionaire by 10days old.
At this same rate, you wouldn't become a billionaire until you are 31 yrs old
.
so you see how far is from millionaire to billionaire?
900 millionaires together have less wealth than one billionaire. It's pretty self-explanatory if you ask me - the system is broken.
