I've googled this question and saw some answers already, but they do not convinced me. What would happen in the economy if everyone in the world wake up and see 1 billion dollars in their house or stuff in where they live. Some people would want to build a huge house or buy lots of apartments but the workers wouldn't want to work anymore since they are rich so that people could only buy buildings already built. It seems like nobody would want to work and people would start to starve until prices get very high (huge inflation) so that the money is still worth something. Some lucky guys who bought apartments would never get poor even when the economy stabilizes later. I'd like answers from people that studied economy or people that know about it somehow well; unlike me. Thank you.
